Here is a pic showing An operator / function between addition and product.

It maps N x N to N.

It is commutative and associative.

(0,n) -> 0

(1,n) -> n

Since that is trivial , it is not written in the picture.

So the table starts at 2.

My apologies for the delay.

I have been thinking about this rather than writing.

I would like to know more before i say more.

Its all very new.

But i can say this is about hyperoperators and a half iterate of 2^(z+1).

The rowwise second order differences are not monotonously increasing. So what is this about?
