Erich Friedman's page "What's Special About This Number" says 26 is the only
number between a square (25) and a cube (27). (Well, the page says "positive
number" but the point is moot if we limit ourselves to real integers). In
fact, it would seem 26 is the only number between two powers. I have
verified this up to 10^7.
