perplexus.info :: Numbers : Primes Around a Square

Primes Around a Square (Posted on 2009-07-10)

A	B	C
D		E
F	G	H

The letters A-H are different digits from 1 to 9.

Read from left to right and top down, the four numbers formed are primes.

There is not just one solution. (Flipping along the diagonal A-H does not present a different solution).

Suppose "0" is allowed, and A cannot have that value, what other unique solutions are available?
