 OFFSET 1,5 COMMENTS A coarse approximation to A341617(n) is the primorial of (n-1), and the terms of this sequence are the quotient A341617(n) divided by the primorial of (n-1). LINKS P. Miska and T. Ward, Stirling numbers and periodic points, arXiv:2102.07561 [math.NT], 2021. FORMULA a(n) = A341617(n)/radical((n-1)!) = A341617(n)/(n-1)# = A341617(n)/A002110(n-1). EXAMPLE For n = 3 it is known that A341617(3) = 2, so a(3) = 2/(3-1)! = 1. CROSSREFS Cf. A341617, A000142, A007947, A002110.
