Comments

Sequence of numbers from A236022 such that A236022(n) > A236022(k) for all k < n.

A236022 = composite numbers n sorted by increasing values of gamma(n) = log_2(n+1) - 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: union of 10 and squares of primes A001248.
