“The theorem states that any elliptic curve over Q can be obtained via a rational map with integer coefficients from the classical modular curve (N) for integer N and is a curve with integer coefficients with an explicit definition. If N is the smallest integer for which the parameterization can be sourced, then it may be defined in terms of mapping generated by a particular kind of modular form of weight two and level N! This, of course, is an integer q-expansion, and can be followed by an isogeny. Der! How could you not know that, Charlie?”
