Harry and Tom each replaced each asterisk
with a digit in such a way that the three
numbers that could be read across and the
two numbers that could be read down were
five different perfect squares each of
which consisted of three different digits
(with no leading zero).
Tom did not use any of the
* * * three-digit squares that
* Harry used. Which three
* * * 3-digit squares consisting
* of three different digits
* * * (with no leading zero) did
neither of them use?
