(In reply to re: An idea
I did not say the product implies the sum. I said the sum implies the product.
Which is equivalent to the contrapositive:
If the product cannot be then the sum cannot be done.
We don't need to check 12 and 18 because their product is a cube.
I was hoping to be able to show p,p or that p,p^(3n+1) reduces to p,p etc.
