Build a 2x2 block Expand to a 2x2x3 without destroying the 2x2x2 block Correct edge orientation Solve two complete layers Permute the remaining corners Orient the remaining corners Permute the final edges

Petrus invented three simple and flexible algorithms to complete the last three steps, which he named Niklas, Sune and Allan. While the method stands alone as an efficient system for solving the Rubik's Cube, many modifications have been made over the years to stay on the cutting edge of competitive speedcubing. Many more algorithms have been added to shave seconds off the solution time, and steps 5+6 or 6+7 are often combined depending on the problems each case presents. Petrus' personal best speedsolve is 13.6 seconds, achieved in 2006. External links[edit]
