Work in progress, maybe?

Multiplication won't make that much of a difference, so there certainly should be some other higher operation, say, $$\uparrow^l$$, where l is the length of the whole word, and even this won't make much difference.

I've wondered the same thing about multiple words, too, but that's in the future I guess.
