well there are infinite such possibilities for a , b , N belonging to set of natural numbers & following condition a*2-b*2=N //N must be even if a2 denotes a^2 ... then a^2=b^2+N ... run a loop for b & find if b^2+ N is forming some perfect square ... if so then that will be corresponding value of a but that is hard to know what can be the maximum value b can take
