So far, besides Googology Wiki Official, there are 2 people have offer the sorting(classes) of numbers, they are Mango523WNR(Divide numbers into Class 0 to Class 23) and Cloudy176(Divide numbers into Class 0 to Class 20)(perhaps there isn't third people)

And I will create new classes in the future perhaps. At that time, the current sorting will be replaced and called "Version 1 Class", then the new sorting "Version 2 Class" will be used.
