User blog:TheMostAwesomer/Hyperfactorials and approximations

I decided to dabble in hyperfactorials for a change and, well, first off, 5 tetra-factorial is pretty big. Approximately E2.184125#(E1.524126#9). I approximated this as E2#9#2, although I'm not sure if this is as accurate as is attainable. It's pretty close, though, I think.

I'm also working on approximating 6 tetra-factorial and 7 tetra-factorial. Googologically speaking, tetra-factorials are pretty weak, but pretty interesting, too.
