this is just combinatorics. is this a permutation or combination? can you repeat values? how many options are there for each case?

also, i'm not sure if it counts 0000000000000000000000000000001 and 0000000000000000000000000000010 as the same.

$$2^{32}=4,294,967,296$$

ya @twvogels, clearly, but technically if zeros are behind the 1 then it's the same value etc
