**How "big" is this number?**

I have had absolutely no sleep for a while, so my math brain has been failing me. Last night, I was working on a problem and I believe that one of my connections is wrong. Is this number countably infinite or uncountably infinite (as

*m*approaches infinity):

[itex]\sum_{n=1}^{m}{(\frac{m!}{n!})^{a}}[/itex]

I feel like it is countably infinite, but I am not sure.

Also, what about just simply (m!)

^{a}as m approaches infinity? If it is uncountable, that will be rather cool, too, as that is what one of my proofs hinge on.
