Extension!

n!1(1,2)2 = n!1(n)2

n!1(2,2)2 = n!1(n! 1(n)2)2

We can also have:

n!1(1,3)2 = n!1(n,2)2

n!1(2,3)2 = n!1(n! 1(n,2)2,2)2

and so on...

We can have (1,4) dimension, (1,5) dimension, etc.

Then, we can apply multiple entry arrays as we did before.

The limit is (1,1,1,...,1,1,2) dimension.
