A181486 Record values in A171919 = number of solutions to n=x*y*z, x+y=z+1. 3

%S 1,2,3,6,8,10,14,16,20,22,24,26,28,34,38

%N Record values in A171919 = number of solutions to n=x*y*z, x+y=z+1.

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

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

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

%F A181486(n) = A171919(A181485(n))

%o (PARI) m=0; for(n=1,1e9, A171919(n)>m | next; print1(m=A171919(n),", "))

%Y Cf. A171919, A181485.
