a(n) is the n-th J_12-prime (Josephus_12 prime) Place the numbers 1..N (N>=2) on a circle and cyclicly mark the 12th unmarked number until all N umbers are marked. The order in which the N numbers are marked defines a permutation; N is a J_12-prime if this permutation consists of a single cycle of length N.
