Medial Magma
In abstract algebra, a medial magma or medial groupoid is a magma or groupoid (that is, a set with a binary operation) which satisfies the identity :(x \cdot y) \cdot (u \cdot v) = (x \cdot u) \cdot (y \cdot v), or more simply xy\cdot uv = xu\cdot yv for all ''x'', ''y'', ''u'' and ''v'', using the convention that juxtaposition denotes the same operation but has higher precedence. This identity has been variously called ''medial'', ''abelian'', ''alternation'', ''transposition'', ''interchange'', ''bi-commutative'', ''bisymmetric'', ''surcommutative'', ''entropic'' etc.Historical comments
