Proposed by K. R. S. Sastry, Dodballapur, India.
Find positive integers x, y, u, v such that
x^2 + y^2 = u^2 and x^2 - xy + y^2 = v^2.
(Equivalently, find a right-angled triangle with integral sides x, y
surrounding the right angle and a triangle with sides x, y surrounding
a 60-degree angle, and with the third side an integer in both cases.)

One possibility is <x,y,u,v> = <15n,8n,17n,13n> for positive
integral n.
