%I A203363 #12 Feb 22 2013 21:39:10 %S A203363 91,85,51,38,33,29,23,19,17,13,11,2,7,1 %N A203363 Denominators of Conway's PRIMEGAME. %C A203363 Numerators are in A202138. %C A203363 Notice that the last number of this sequence is 1, meaning that the last number in the "prime producing machine" is an integer, namely 55. Thus, if each multiplication by the previous numbers of the "machine" fails to give an integer, this one will, and it will be a multiple of 55. %o A203363 (Haskell) %o A203363 a203363_list = [91, 85, 51, 38, 33, 29, 23, 19, 17, 13, 11, 2, 7, 1] %o A203363 -- _Reinhard Zumkeller_, Jan 24 2012 %Y A203363 Cf.
