Comments

Sequence of numbers from A236020 such that A236020(n) > A236020(k) for all k < n.

A236020 = natural numbers n sorted by increasing values of k(n) = log_tau(n) (sigma(n)), where sigma(n) = A000203(n) = the sum of divisors of n and tau(n) = A000005(n) = the number of divisors of n.

Conjecture: subsequence of A094348.
