Square from primes
HARRY, Tom and I were looking to find 5-digit perfect squares that consisted of a 2-digit prime followed by a 3-digit prime, neither prime starting with a zero.
We each found a different example. My 2-digit prime was the same as Harry’s and my 3-digit prime was the same as Tom’s.
Which square was found by (a) Harry, (b) Tom?
