Examples can also be constructed using the method of Howe/Leprévost/Poonen (Forum Math. 12 (2000) 315–364). For example, the plane quartic
x^4 + y^4 + 1 + r^12*x^2 + r^12*y^2 + r^7*x^2*y^2 = 0
(where r^3 - r + 1 = 0) has 56 points.

This upper bound follows from Theorem 2 (p. 89) of the cited reference, because 27 = 5^2 + 2.
