%I A251556 #17 May 15 2018 16:45:30 %S A251556 1,2,3,4,5,6,7,12,17,24,40,42,50,86,107 %N A251556 Conjectured values of n which are the minimal cycle representatives of finite cycles in the permutation of the natural numbers defined by A098550. %C A251556 At present we do not know for certain that 11, 29, 36, etc. are really missing, since the status of the cycle containing 11 is not known. It appears to be infinite (see A241412). %C A251556 For other values that are known to be in the sequence see the Havermann link. %C A251556 A251411 is a subsequence. %H A251556 Hans Havermann, <a href="http://chesswanks.com/num/a098550loops&chains.txt">Loops and unresolved chains for map n -> A098550(n) trajectories</a> %H A251556 David L.
