Increase the number! [NOTATION INFO COMING] Fx is 10^^x Gx is 10^^^x and Hx is 10^^^^x oh, and [a]x is 10{a}x There is J (10{x}10) and K/L (10{{1/2}}x) too. Don't forget [a,b]x! ({10,x,a,b+1} but {10,10,x,b} when a=0) And L is just [0,2]! N is [0,x]10=[0,0,1]x! and 3 args is like 2args but with a c+1 and another edge case: {10,10,10,x,c}. (this can be extended very naturally to higher entries)
