Circle with radius r (r is an integer) has point P inside it. Center of circle is M(r,r).
Points A,B,C are on the circumference: PA, PB and PC are different integers.
AngleAPB = angleBPC = angleCPA = 120 degrees (of course!).
I'm looking for hints/suggestions as to simplest way to "find" such circles,
and get coordinates of point P. Anybody got "short cuts"? Thanks.
