How does it look like ? Analogues of Bohr-Mullerup etc ? Hence the connection to the hyperoperators. regards tommy1729 RE:  Beyond Gamma and Barnes-G - MphLee - 12/28/2014 Mhh maybe I have made some errors but the solution of the eqation seems to have some problems in the first values... that should make it not determinate for natural values Let assume that then because of the limit is not determinate (multivalued?) I'm not sure how to continue in this case... maybe we can start by fixing the value of and continue with the recursion ... So actually the solution is of the form for some ? ------ Btw I see the relation with the Bennet's commutative Hyperoperations (denote it by )! This is like a kind of "Hyper-factorial" that uses the Bennet's Hyperops.. -------------- Edit: I think that the correct forumla is something of the form Given or
