COMMENTS

a(n) can also be calculated by transforming (3,18,8) applying the binomial transform twice. Cf. A098384.

LINKS

Table of n, a(n) for n=0..6.

EXAMPLE

The hook-type least prime signatures with exactly three primes begin 30,60,120,.. therefore a(n) begins A002033(30,60,120,...) = 13,44,132,...

CROSSREFS

Cf. A098348, A098384.
