A [0] corresponds to ω.

A [...[[n...]]] with p brackets corresponds to ωp+n.

[A,B] approximately corresponds to B+A in the FGH. A and B can be any expression. For example, 0,1],[0 corresponds to ω^ω+ω^2.

[0,A,B] approximately corresponds to ω^(Β+Α) in the FGH. For example, [0,[0,2],1] corresponds to ω^(ε0+ω^3).

[0,0,A,B] approximately corresponds to ε(Β+Α) in the FGH. For example, [0,0,2,1] corresponds to ε(ζ0+2).

[0,0,0,...,0,0,1] with n 0’s corresponds to φ(n-1,0) in the FGH.
