//! This library implements the MNT4_753 curve generated in
|
|
//! [[BCTV14]](https://eprint.iacr.org/2014/595). The name denotes that it is a
|
|
//! Miyaji--Nakabayashi--Takano curve of embedding degree 4, defined over a 753-bit (prime) field.
|
|
//! The main feature of this curve is that its scalar field and base field respectively equal the
|
|
//! base field and scalar field of MNT6_753.
|
|
//!
|
|
//! Curve information:
