infinity

*Infinity* ($\infty$) is a concept with various interpretations. The common theme is that $\infty$ is larger than whatever is usual in a given context; the usual stuff being called *finite* in contrast. Typically, this means larger than any natural number (although one sometimes considers infinite nonstandard natural numbers on the one hand, or considers infinity to be beyond a given class of transfinite ordinals on the other hand).
