OEIS Sequences

Highly composite numbers: numbers n where d(n), the number of divisors of n (A000005), increases to a record. A2182
Smallest number k such that the symmetric representation of σ(k) has at least one part of width n. A250070
Triangle of generalized Stirling numbers S2,2(n,k) read by rows (n>=1, 2<=k<=2n). A78739
a(n) = n*(n-1)2*(n-2). A47928
Numbers n such that, for some numbers (j,k), j<=k, n is the smallest positive multiple of j (or more) of the first k positive integers. A94348
