User talk:Username5243/XKCD Notation Reference

Your extended up arrow notation does not terminate. Take the example 3^1,23=3^2,23 (rule 2) = 3^1,23^1,23

The problem is with rule 2. Instead of a^1,cb=a^c,b-1a, you need a^1,cb=a^b,c-1a. By the way, the growth rate of f(n)=n^1,nn is about \(f_{\omega^2}(n)\). Maybe called Googology Noob (talk) 05:15, March 9, 2016 (UTC)
