OEIS Sequences

a(n) = a(1) + a(2) + ... + a(n-1) + a(m) for n >= 3, where m = 2·n - 3 - 2^p+1 and p is the unique integer such that 2^p < n - 1 <= 2^p+1 with a(1) = a(2) = 1. A49940

L.g.f.: -log(1 - ∑_n>=1 x^n²) = ∑_n>=1 a(n)*xⁿ/n. A219331

a(n) = (5·n+1)*(5·n+4). A1545

Numbers k such that k + sum_of_digits(k) is a cube. A84661

Numbers having four 2's in base 8. A43432

Numbers n such that 9·10ⁿ + 2·R_n - 1 is prime, where R_n = 11...1 is the repunit (A002275) of length n. A103093

Numbers n such that if n = a U b (where U denotes concatenation) then abs(σ*(a) - σ*(b)) = abs(σ*(n) - n), where σ*(n) is the sum of the anti-divisors of n. A239687

A(n, k) is the k-th number b > 1 such that b^prime(n+i-1) == 1 (mod prime(n+i)²) for each i = 0..2, with k running over the positive integers; square array, read by antidiagonals, downwards. A319060

a(n) = (12·n + 2)¹⁰. A17554
