This is beyond pentational arrays.
So exponentation:
(x),(1)(y) = (0,0,...,0,0,x) (y 0's)
Tetration:
(x),(2)(y) = (x),(y)
Pentation:
(x),(3)(y) = (1),(1)...(1),(1),(x) (y-1 (1)'s)
And beyond!
(x),(z)(y) = (1),(z-1)(1)...(1),(z-1)(1),(z-1)(x) (y-1 (1)'s).
For example
Kungulus = {10,10 (1),(3)(100) 2}
Kungulusplex = {10,10 (1),(3)(kungulus) 2}
Quadrunculus = {10,10 (1),(4)(100) 2}
We define {X,2,1,2}:
(x),(0,1)(y) = (x),(X)(y)
{X,3,1,2}:
(x),(1),(0,1)(0,1)(y)
{X,4,1,2}:
(x),(1),(1),(0,1)(0,1)(0,1)(y), etc.
