OEIS Sequences

a(n) = ∑_d∣n d·2^n-d. A90879

Expansion of Gaussian product of arithmetic mean and Lehmer mean evaluated at 1 + 4·x. A78801

If k is a number with exactly two distinct decimal digits, say a and b, neither of which is 0 (i.e., a member of A101594), define the self-complement of k, SC(k), to be the number obtained by replacing a with b and vice versa. E.g. SC(232233) = 323322. Sequence contains numbers n such that n and SC(n) are relatively prime. A83984
