Array of

The array of operator is an operator used to accompany Array Notation and BEAF.

Usage
When used on two integers, the "array of" operator (written $$a\ \&\ b$$) means $$\underbrace{\{a,a,a,a,\ldots\}}_b$$. This is primarily used in legiattic arrays.

Bowers also uses $$a^n\ \&\ b$$ to mean solving an n-hypercube (sidelength a) of b 's. The exponent on the left side of the operator should never be solved as a normal exponent unless $$n = 1$$.

To represent superdimensional arrays, Bowers uses $$a\underbrace{\uparrow\uparrow\ldots\uparrow\uparrow}_x n\ \&\ b$$ or $$\{a,n,x\}\ \&\ b$$, where the sidelength of the hypercube is a, n is the dimension, and x is the superdimension.
