 OFFSET 1,1 COMMENTS Largest term is a(3265903)=1097393447. In defense of this sequence, let me say that when one is studying a sequence for which no formula or recurrence is known, one line of attack is to look at the largest prime factors of the terms. This might reveal some hidden property, or suggest a connection with a different sequence. - N. J. A. Sloane, Jan 17 2012 LINKS Zak Seidov, Table of n, a(n) for n = 1..10000 CROSSREFS Cf.
