not sure the right words to use..

on a graph there is an x & y axis

given a domain were the x axis were ordinal numbers or cardinal numbers or veblen heirarchy numbers or tree numbers & the y axis were fast growing functions or hyper operations or veblen functions or some other fast growing function, if you were to diagonalize across the domain, what would it approach (limit), what is the size of that set (summation), etc
