Task description error?
The task description asserts:
- the nim-product of a Fermat power (22k) 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.)
