 OFFSET 1,3 COMMENTS Multi-recursive sequence suggested by A004000 : 5th level. If A004000 is a level 2 recursion and A087817 is 3rd and A087836 is 4th, this is sequence is the 5h level. Other multi-recursives approximate this sequence for initial terms: A087845, A087847 Benoit Cloitre's sequence is: d = Table[Ceiling[n^.56], {n, 1, digits}] LINKS MATHEMATICA Conway[1] = Conway[2] = 1; Conway[n_Integer?Positive] := Conway[n] = Conway[Conway[Conway[Conway[Conway[n - 1]]]] ] + Conway[n - Conway[n - 1]] digits = 256; a = Table[Conway[n], {n, 1, digits}] CROSSREFS Cf. A028310, A004000, A087817, A087836, A087845, A087847. Sequence in context: A033810 A023965 A087847 * A002024 A123578 A087845 Adjacent sequences:  A107433 A107434 A107435 * A107437 A107438 A107439 KEYWORD nonn AUTHOR Roger L, Bagula (tlbagulatftn(AT)yahoo.com), May 26 2005 STATUS approved
