Every run of digits of n in base 3 has length 2. A33001
Palindromic numbers in bases 3 and 9 written in base 10. A259386
T(n,k) = Number of permutations of 1..n+2·k-1 with each element displaced by at least k. A183244
Expansion of e.g.f.: exp(exp(x) - 4·x - 1). A346739
Expansion of ∏k>=1 1/((1-x3·k-1)*(1-x3·k-2))k. A262883
Triangle read by rows: T(n,k) is number of labeled bipartite graphs with n nodes and k edges. A117279
Primitive numbers n such that 1/n is in the Cantor set. A173793
Place n equally spaced points on each side of a square, and join each of these points by a chord to the 3·n new points on the other three sides: sequence gives number of regions in the resulting planar graph. A367278
Table read by antidiagonals: Place k equally spaced points on each side of a regular n-gon and join every pair of these n·k points by a chord; T(n,k) (n >= 3, k >= 0) gives the number of regions in the resulting planar graph. A367304
Irregular triangle in which row n has primitive numbers k such that 1/k is in the Cantor set and the fraction 1/k has period n. A173800
