OEIS Sequences

Numbers that are the sum of 9 positive 9th powers. A3398

a(n) = floor(c·s*a(n-1)) + floor(d·r*a(n-2)), where r = (1+sqrt(5))/2, s = r/(r-1), c = 1, d = 1, a(0) = 1, a(1) = 1. A275856

a(n) is the number of integers·that can be written x = (2^c(1) - 2^c(2) - 3·2^c(3) - 3²*2^c(4) - ... - 3^m-2*2^c(m) - 3^m-1) / 3^m for integers c(1), c(2), ..., c(m) such that n = c(1) > c(2) > ... > c(m) > 0 and c(1) - c(2) ≠ 2 if m >= 2. A131450

Starting numbers that require more iterations of the map x->A359194(x) (binary complement of 3n) to reach 0 than any smaller number. A359219
