Talk:Nimber arithmetic

Task description error?

The task description asserts:

the nim-product of a Fermat power (2^{2^k}) and a smaller number is their ordinary product

But 16 is a fermat power and inspecting implementations here, I see that they would produce 11112 as the result for 7 ⊗ 16

(Also, the definitions require reasoning about infinities of negative numbers but the task includes no discussion of how that is handled.)
