how is that even remotely "Lets define veblen recursion as usually"

how does phi(a,0) = w^a ? this makes no sense

perhaps you meant phi(0,a)?

why do you believe phi(G_0,0) = w^^w?

perhaps you mean epsilon_0?

Actually there is no "accepted" standard for hyper operation on  ordinals, and i'm happy to have things that way, even though sometimes in chat we abuse notation for a^^b to mean "power tower of a, b tall" we must remember this is not standard and thus anything past two arrows or b=w should be treated as undefined.
