EXAMPLE
|
a(1)=0=19^2-17^2-11^2+7^2 (0 already requires 19)
a(2)=643=23^2+19^2-13^2-7^2-5^2-2^2 (requires 23)
a(3)=1172=29^2+23^2-13^2-5^2-2^2
a(4)=2013=31^2+29^2+17^2-7^2-5^2-2^2
a(5)=2974=37^2+29^2+23^2+17^2-7^2-3^2+2^2=37^2+31^2+23^2+13^2-7^2-3^2+2^2
(two representations with the same maximum term)
