• a(0) = 1; for n>0, a(n) = number of distinct sums of subsets of {1, 1/2, 1/3, 1/4, ..., 1/n} (allowing the empty subset).at n=19A072207
• Let x(0)x(1)... x(q-1)x(q) denote the decimal expansion of a number n. The sequence lists the numbers such that n and the number represented by its middle digits x(1)x(2)...x(q-1) have the same distinct prime divisors.at n=37A243812
