Seriously, planet, that's the only problem you could find with it?

The whole thing is ill-defined.

What's "the nth symbol"?

Also, this isn't "an ordinal notation" unless you can write every ordinal (up to the notation's limit) with it. How would you write e1? e_w? e_z0? e_(z0+w)?

At any rate, the definition of ΔΔw doesn't make any sense because "w triangles" is not a valid notation. You can't write down a infinitude of triangles...
