211 (number)
211 (two hundred ndeleven) is the natural number following 210 and preceding 212. It is also a prime number. In mathematics 211 is an odd number. 211 is a primorial prime, sum of three consecutive primes (67 + 71 + 73), Chen prime, centered decagonal prime, and self prime. 211 is the smallest prime separated by 10 or more from the nearest primes (199 and 223). It is thus a balanced prime and an ''isolated prime''. 211 is a repdigit in base 14 (111). Multiplying its digits, it is still a prime (2), and adding its digits, it is square (4). Rearranging its digits, 211 becomes 121, which also is a square. Adding any two of its digits will be prime (2 or 3). 211 is a super-prime. In science and technology 2-1-1 is special abbreviated telephone number reserved in Canada and the United States as an easy-to-remember three-digit telephone number. It is meant to provide quick information and referrals to health and human service organizations for both services from charities and ...

213 (number)
213 (two hundred ndthirteen) is the number following 212 and preceding 214. In mathematics 213 and the other permutations of its digits are the only three-digit number whose digit sums and digit products are equal. It is a member of the quickly-growing Levine sequence, constructed from a triangle of numbers in which each row counts the copies of each value in the row below it. As the product of the two distinct prime numbers 3 and 71, it is a semiprime, the first of a triple of three consecutive semiprimes 213, 214, and 215. Its square, 2132 = 45369, is one of only 15 known squares that can be represented as a sum of distinct factorials In mathematics, the factorial of a non-negative denoted is the product of all positive integers less than or equal The factorial also equals the product of n with the next smaller factorial: \begin n! &= n \times (n-1) \times (n-2) \t ....

Totient
In number theory, Euler's totient function counts the positive integers up to a given integer that are relatively prime to . It is written using the Greek letter phi as \varphi(n) or \phi(n), and may also be called Euler's phi function. In other words, it is the number of integers in the range for which the greatest common divisor is equal to 1. The integers of this form are sometimes referred to as totatives of . For example, the totatives of are the six numbers 1, 2, 4, 5, 7 and 8. They are all relatively prime to 9, but the other three numbers in this range, 3, 6, and 9 are not, since and . Therefore, . As another example, since for the only integer in the range from 1 to is 1 itself, and . Euler's totient function is a multiplicative function, meaning that if two numbers and are relatively prime, then . This function gives the order of the multiplicative group of integers modulo (the group of units of the ring \Z/n\Z). It is also used for defining the RSA en ...

+212
All phone numbers in Morocco are 9 digits in length (excluding the leading 0). Morocco uses a closed numbering plan, i.e. the prefix is not omitted for local calls. This is necessary because the same geographic area can be served by several prefixes. Casablanca, for instance, has 10 prefixes. Fixed and mobile prefixes belong exclusively to one phone company. On the following list, fixed networks are indicated by the following letters: I = Maroc Telecom (fixed), O = Orange Maroc (NGN), W = INWI (Maroc Connect) (fixed NGN), X = INWI (Maroc Connect) (fixed GSM(?)) List The disputed territory of Western Sahara de facto uses the ranges owned by Morocco. The ranges in Western Sahara are +212 5288-XXXXX, and +212 5289-XXXXX. History 1990 - Transition to 6-digit numbers In 1990, 6-digit phone numbers were introduced. 199x - Transition from 6-digit to 7-digit numbers 2000 - Transition from 7-digit to 8-digit numbers On 2000-10-13 at 23:00 UTC, the numbering area in Morocco ...

Area Code 212
Area is the quantity that expresses the extent of a region on the plane or on a curved surface. The area of a plane region or ''plane area'' refers to the area of a shape or planar lamina, while '' surface area'' refers to the area of an open surface or the boundary of a three-dimensional object. Area can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape, or the amount of paint necessary to cover the surface with a single coat. It is the two-dimensional analogue of the length of a curve (a one-dimensional concept) or the volume of a solid (a three-dimensional concept). The area of a shape can be measured by comparing the shape to squares of a fixed size. In the International System of Units (SI), the standard unit of area is the square metre (written as m2), which is the area of a square whose sides are one metre long. A shape with an area of three square metres would have the same area as three such squa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
212 (song)

Type 212 Submarine
The German Type 212 class (German: U-Boot-Klasse 212 A), also Italian ''Todaro'' class, is a diesel-electric submarine developed by Howaldtswerke-Deutsche Werft AG (HDW) for the German and Italian navies. It features diesel propulsion and an additional air-independent propulsion (AIP) system using Siemens proton exchange membrane (PEM) compressed hydrogen fuel cells. The submarines can operate at high speed on diesel power or switch to the AIP system for silent slow cruising, staying submerged for up to three weeks with little exhaust heat. The system is also said to be vibration-free, extremely quiet and virtually undetectable. Type 212 is the first fuel cell propulsion system equipped submarine series. Development At the beginning of the 1990s the German Navy was seeking a replacement for the Type 206 submarines. Initial study started on a Type 209 improved design, with AIP capability, called Type 212. The final programme started in 1994 as the two navies of Germany and I ...

Maglan
Maglan (Hebrew: מגלן. Also known as Unit 212 or Sayeret Maglan) is an Israeli sayeret (''reconnaissance'') unit, which specializes in operating behind enemy lines and deep in enemy territory using advanced technologies and weaponry. Though Maglan is part of the IDF's Commando Brigade, its operators undergo basic training with the Paratroopers Brigade. The unit's name means "Ibis" (In Hebrew: Maglan). According to one officer, "Maglan is a bird that knows how to adapt in every situation." A relatively new unit, Maglan was founded in 1986, but its existence was only declassified in 2006. History Very little is known about the unit, only that the force performs top secret operations behind enemy lines, deep within hostile territory. The IDF keeps Maglan's designated missions a secret and gives no information about it or the operations in which the unit takes part. The secretive unit has clocked-up countless hours of high-risk operations conducted well behind enemy lines—mos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
