Dec 10, 2012 at 2:25	comment	added	Artes		@CBenni You might play around e.g. with this : `Table[ Reduce[ Mod[2^n - n, 10^4] == 0 && k 10^(4) < n < (k + 1) 10^(5 - 1), n, Integers], {k, 10}]`, while for `Mod[2^n - n, 10^5]` there is only `n == 48736`.
Dec 9, 2012 at 17:54	comment	added	CBenni		Reduce[ Mod[ 2^n - n, 10^k] == 0 && 10^(k-1) < n < 10^k, n, Integers] gives me the same error for k>=5. But in general, shouldnt this be evaluated almost immediately?
