In order to generate more traffic on this blog, I thought I’d occasionally introduce a puzzle for you to work on.

The first puzzle.

Nine digits, other than zero, can be arranged uniquely to form four numbers which are all squares:-

9 (32) 81 (92) 324 (182) 576 (242)

What is the smallest possible square number comprising all nine digits together, and the largest square number comprising all nine digits together?
