It's basicaly up-arrow notation.It has a limit growth rate of \(f_{\omega}(n)\).

Maybe in future you could extend it furthur by adding more things to it?

Maybe you could invent your extended operators.....and than arrays?

Only if you want,anyway!

But for now it's too sinilar to Knuth up-arrows.
