Is Infinity a Noun?

English has this amazing thing where there's actually a particular order that adjectives and determiners have to take. So you can have this incredible length of adjectives that come before the actual head noun of the phrase, but they have to follow a specific order. And numerals have to be right up the front like it can't be just before. The numbers like one to infinity except for the number infinity itself are actually the numerals which operate a little bit differently.
