OEIS Sequences

Numbers n such that (10²ⁿ⁺¹+54·10ⁿ-1)/9 is prime. A107127

Heinz numbers of integer partitions of n into distinct perfect squares (A033461). A324587

Odd interprimes not divisible by 3. A72573

Triangle read by rows: T(n,k) is the number of permutations of {1,2,...,n} having k increasing even cycles (0<=k<=n). A cycle (b(1), b(2), ...) is said to be increasing if, when written with its smallest element in the first position, it satisfies b(1)<b(2)<b(3)<... . A cycle is said to be even if it has an even number of entries. For example, the permutation (18)(2347)(569) has 2 increasing even cycles. A186764

Array read by antidiagonals: T(n,k) is the number of rooted strong triangulations of a disk with n interior nodes and 3+k nodes on the boundary. A341856

Triangle read by rows, coefficients of the generalized Eulerian polynomials A_{n, 3}(x) in descending order. A225117

Number of equivalence classes of 4 X n binary matrices when one can permute rows, permute columns and complement columns. A6380

Growth function (or coordination sequence) of the infinite cubic graph corresponding to the srs net (a(n) = number of nodes at distance n from a fixed node). A38620

Odd interprimes divisible by 7. A126229
