 A182762 Number of ordered factorizations of A025487(n) as A025487(j) * A025487(k). 4
 1, 2, 3, 2, 4, 4, 5, 6, 2, 6, 3, 8, 4, 7, 6, 10, 6, 8, 9, 4, 12, 2, 4, 8, 9, 12, 8, 14, 4, 8, 10, 10, 15, 12, 16, 6, 12, 3, 12, 11, 6, 18, 4, 5, 16, 18, 8, 16, 6, 14, 12, 12, 21, 2, 8, 10, 20, 20, 10, 20, 9, 16, 13, 18, 24 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,2 COMMENTS A025487(j) and A025487(k) need not be distinct. Because multiplying two members of A025487 always produces a member of A025487, the value of this function for all nonmembers of A025487 is 0. LINKS Amiram Eldar, Table of n, a(n) for n = 1..10000 FORMULA a(n) = A000005(A181815(n)). EXAMPLE 36 has three different ordered factorizations into two members of A025487 (36 = 1*36 = 6*6 = 36*1). Therefore, since 36 = A025487(11), a(11) = 3. CROSSREFS Cf. A000005, A025487, A181815.
