Comments

The sequence lists all m=A171919(n) such that m > A171919(k) for all k < n.

The indices n for which these record values are taken are given in A181485.

Larger numbers of solutions do occur, for example A171919(388778796252000) = 38 (although this may not even be a record). - Georgi Guninski, Jan 04 2011
