Yep, seems to be so. I mean, it shouldn't be very surprising that among all possible lengths and bases there are some of length 1, would be more astonishing if there wasn't any. But it's not like it's somehow less worthy than other mathematical games. After all, there could have been some meaningful property hidden in there. Doesn't appear so in this case, but you'd never know beforehand.
