//! This library implements the MNT4_298 curve generated by
|
|
//! [\[BCTV14\]](https://eprint.iacr.org/2014/595). The name denotes that it is a
|
|
//! Miyaji--Nakabayashi--Takano curve of embedding degree 4, defined over a
|
|
//! 298-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_298.
