OEIS Sequences

Number of compositions of n into 5 ordered relatively prime parts. A743

a(n) = n⁴ + n³ + n² + n. A27445

Table read by antidiagonals: T(n,k) is the number of n X k 0..1 arrays with every row and column least squares fitting to a nonnegative-slope straight line, with a single point array taken as having zero slope. A222862

Irregular table read by rows: The number of k-faced polyhedra, where k >= 4, created when an n-bipyramid, formed from two n-gonal pyraminds joined at the base, is internally cut by all the planes defined by any three of its vertices. A338825

Sums of distinct powers of 12. A33048

Numbers k such that k+1 is a prime, k+2 is twice a prime, and k+3 is three times a prime. A278583

Least integer k>1 such that sqrt(k)/log(k) exceeds n. A262058

a(n) is the smallest number which can be represented as the sum of n distinct nonzero squares in exactly 2 ways, or -1 if no such number exists. A374287

Triangle read by rows: T(n,k) is number of hex trees with n edges and level of first leaf (in the preorder traversal) equal to k (1 <= k <= n). A126186
