OEIS Sequences

a(n) = T(n, floor(n/2)), T given by A026519. A26530

a(n) = least k such that the remainder when 7^k is divided by k is n. A119715

Generalized 17-gonal (or heptadecagonal) numbers: m*(15·m - 13)/2 with m = 0, +1, -1, +2, -2, +3, -3, ... A303305

a(n) = T(2·n, n), where T is given by A026519. A26525

Row sums of A078938. A78940

Odd positive integers a(n) such that for every integer m == 3 (mod 4) there exists a unique representation of the form m = a(l) + 2·a(s), but there are no such representations for m == 1 (mod 4). A145818

Numbers a(n) are obtained by the direct application of sieve of Eratosthenes for A000695: retaining A000695(2)=4, we delete all multiples of 4, which are more than 4; retaining A000695(3)=5, we delete all multiples of 5, which are more than 5, etc. A152021
