User blog comment:I am a McCree God/100^99^98...^1/@comment-30754445-20171024162419

Your approximation is wrong.

This number is exactly 100!1 in Hollom's factorial notation:

100!1 ~ 10^10^10^...[96 tens]...^10^10^10^183230

In Saibian's Hyper-E this can be written as E183230#96

And in LOS it can written as G2-1-1-97-5-183230
