 OFFSET 1,2 COMMENTS By definition all terms are partition numbers. All members of A049575 are in this sequence. Conjecture: the only composite numbers in this sequence are 15, 22, and 77. - Jon E. Schoenfield, Feb 05 2014 LINKS EXAMPLE 15 is in the sequence because the divisors of 15 are 1, 3, 5, 15, which are also partition numbers. CROSSREFS Cf. A000041, A027750, A049575, A236103, A236105, A236107, A236108, A236110, A236111.
