There was a crossnumber puzzle (a crossword with numbers) in Chalkdust magazine recently. The answer to one question was a pandigital square (base 10) and I got to thinking what happens in other number bases.

After some algebraic playing around (and a quick bit of coding) I found out how many pandigital squares there are in other number bases and submitted the result to the OEIS.
My entry was updated by their helpful editors they've published sequence A258103.
