 OFFSET 1,1 COMMENTS This sequence forms the diagonal of the table (A095904) containing all of the integers >= 2, ordered by prime signature. The first row of the table is A025487 (starting with n=2), The first column of the table is the primes (A000040). The description for this sequence specifies "prime-containing" to exclude the prime signature for 1, which is also excluded from A095904. LINKS EXAMPLE The 5th prime-containing prime signature (i.e. excluding the prime signature for 1) is {1,2}. The 5th integer to have that prime signature is 44 (see A054753 for a list). Therefore a(5) is 44. CROSSREFS Cf. A025487, A000040, A095904.
