Question 331491
A Pythagorean triple is a set of three positive integers, 

{a, b, c} such that {{{a^2+b^2=c^2}}}

Examples are {3,4,5}, {5,12,13}, {7,24,25}, {8,15,17}, {9,40,41}


They can be found by choosing any two positive integers m and n,
where m > n
and substituting in these three equations:

{{{system(a=m^2-n^2,
b=2mn,
c=m^2+n^2)}}}
