A277231 - cp's OEIS frontend

A277231 Irregular triangular array T(n, k) giving in row n the so-called slope of the Ferrers diagram of the k-th partition of n into distinct parts. The partitions of n are taken in Abramowitz-Stegun order but with decreasing parts. See a comment for the definition of this 'slope'.
