Formula

A247796(a(n)) < a(n).

A168046(a(n)) = 1. [Editor's note: This is obviously wrong. Certainly another sequence number was meant. Please edit or inform us if you find the correct reference.]

a(n) = A039691(n+10) up to a(64) = 118, but a(65) = 119 is not in A039691. - M. F. Hasler, Jan 26 2018
