Explicit example     
Everett Howe
05-20-2010 22:06
In his Harvard notes, Serre gives an explicit example (which appears with a small misprint): The biquadratic extension of F_16(x) defined by
y^2 + y = x + r/x
z^2 + z = x + r/(x+1)
where r satisfies r^2 + r + 1 = 0.

This upper bound follows from Cor. 2 of Sec. 4 of the cited reference.
