User blog:SuperSpruce/T array function stuck at Gamma 0

The T array function (probably) works fine until Γ0. Here’s why it gets stuck at this ordinal:

The expression Tn[0{0,1}2] should have a growth rate of ψ(ΩΩ2). But using the rules, it turns into [0{[0{[...{[0{[0,2]}2]}...]}0]}0] with n {[‘s. This is just the fundamental sequence for Γ0 in this notation.

Note that I’m using the rules I defined in part 4 of the T array function.

I think either the dimensional array rule or the catastrophic rule is to blame.

Can anybody please help me find out what is wrong and help me fix it?
