Ok, I checked the HAN page on the googology site. It seams that something similar has already been defined by Hollom. Indeed a[b+2]! = a!b and we genealized our notations in different ways. I found out that a tetrational version of the factorial was concieved defining "tetrofactorial" always by Hollom. So the only new thing here is the operatorial.
