a(1) = 1. Thereafter, if A007947(a(n-1)) is in A002110, a(n) = smallest prime not already a term (condition [A]). Otherwise, if q is the greatest prime < Gpf(a(n-1)) which does not divide a(n-1), a(n) is the least novel multiple of q,(condition [B]). A376865

Row sums of triangle A099527, so that a(n) = ∑_k=0..n coefficient of z^k in (2 + 3·z + z²)^n-[k/2], where [k/2] is the integer floor of k/2. A99528
