Number of compositions of n with no part divisible by the next. A328460

Numbers k such that binomial(6k, k) + 1 is prime. A125245

Number of permutations of {1,2,...,n} containing exactly 5 occurrences of the pattern 132. A138163

Analog of A006684 for the 7x+1 problem (cf. A133421). A133425

Total sum of the hook lengths over all partitions of 2n-1 having exactly n parts. A301499

Triangle read by rows: T(n,k) is the number of planar tanglegrams of size n with 0 <= k < n leaf-matched pairs. A leaf matched pair is a pair of non-leaf vertices (u,v) in the tanglegram such that the induced subtrees rooted and u and v also form a tanglegram (equivalently, the leaves in these two subtrees are matched by the matching that forms the original tanglegram). A349409

Partial sums of the number of active (ON, black) cells in n-th stage of growth of two-dimensional cellular automaton defined by "Rule 595", based on the 5-celled von Neumann neighborhood. A273142
