Abstract: Supercharacters have recently been proposed as a sort of stand-in for the characters of $ p$-groups. If $ q>1$ is a prime power, then every set of $ q$-powers that contains $ 1$ is both a set of superdegrees and a set of superclass sizes. Moreover, if $ r$ and $ s$ are integers that are greater than $ 1$, then there is an algebra with exactly $ r$ superdegrees and exactly $ s$ superclass sizes. These results are direct analogs of results from the theory of $ p$-groups.
