%N Indices of records in A112801 = number of partitions of 2n-1 into three numbers with two distinct prime factors each.

%C It appears that starting from a(64)=104 on, the sequence consists exactly in the numbers (larger than 103) congruent to 2 mod 3.

%F For n >= 64, a(n) = 3n - 88. (Conjectured.)

%o (PARI) m=0;for(i=1,1000,m<(m=max(A112801(i),m))&&print1(i","))
