Records of minima of A154333, difference of a cube minus the next smaller square. A179386

Triangle read by rows: T(n,k) is the number of strict multiset partitions of normal multisets of size n into k blocks, where a multiset is normal if it spans an initial interval of positive integers. A330787

a(n) is the least positive integer k such that Mordell's equation y² = x³ - k has exactly n integer solutions with y >= 0. A392395

a(n) = a(1) + a(2) + ... + a(n-1) + a(m), where m = 2^p+1 + 2 - n and p is the unique integer such that 2^p < n-1 <= 2^p+1, starting with a(1) = a(2) = 1. A49941

Least k such that k·10ⁿ-9, k·10ⁿ-7, k·10ⁿ-3 and k·10ⁿ-1 are all prime. A64432
