A002113) are excluded. 78 is a record (cf. A065199) of the number of 'Reverse and Add' steps needed to reach a palindrome. %C A065325 First term not congruent to 15 mod 18 is a(135) = 2000688, thereafter residues 6 and 15 appear in larger clusters; first residue different from 15 and 6 is at a(1215) = 16902780. - Klaus Brockhaus, Jul 14 2003 %H A065325 <a href="/index/Res#RAA">Index entries for sequences related to Reverse and Add!</a> %Y A065325 Cf.
