On Jan 4 , 2012 Emmanuel Vantieghem sent to me an email pointing
out that 14449 is the smallest
prime that is the concatenation of two squares in two ways:
14449 = 12^2&7^2 = 14449
See also OEIS
One day later he found all the primes of this type less than
10^14 and published OEIS
of these primes is thrice such concatenation"
Q. Find one prime (if the smallest the
better) that is the concatenation of
only two squares in three ways.
