This sequence is intended to help spot these irregularities and perhaps lead to further rules, which probably have no analogy in A354169. %C A355714 In most cases A090252(A355176(n)) equals prime(a(n))*p where p is prime. Surprisingly p is in many cases greater than prime(a(n)). %C A355714 Is this sequence infinite? %F A355714 A090252(A355176(a(n))) <> A000040(a(n))^2. %F A355714 A000040(a(n)) divides A090252(A355176(a(n))). %F A355714 A000040(a(n)) divides A090252(2*A355176(a(n))+1). %Y A355714 Cf.
