OEIS Sequences

Number of unlabeled bicolored bipartite graphs on 2n nodes having n nodes of each color with no edges between vertices of the same color and edges having two colors and allowing the node color classes to be interchanged. Edge colors are swappable (permuted by the symmetric group). A331013

n written in fractional base 8/6. A24648

Numbers n such that prime(n) + {1, 2, 3, 4, 5, 6} are all products of the same number of primes (not necessarily all distinct). A255202

a(n) = n*(n² - 1)*(n+2)*(2·n⁵ + 14·n⁴ + 49·n³ + 91·n² + 90·n + 18)/324. A64203

Triangle read by rows: T(n,k) is the number of permutations p of [n] such that the number of inversions of the word formed by the leading entries of the blocks of p is k. A block of a permutation is a maximal sequence of consecutive integers which appear in consecutive positions. For example, the permutation 5412367 has 4 blocks: 5, 4, 123, and 67; their leading entries are 5,4,1, and 6 and the word 5416 has 3 inversions. A186372

Numbers k such that, taken together, the base-10 and base-b expansions of k are pandigital for some b < 10. A174596
