//! 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.
|
|
//!
|
|

|
|
//! Curve information:
|
|
//! * Base field: q = 475922286169261325753349249653048451545124879242694725395555128576210262817955800483758081

//! * b = 423894536526684178289416011533888240029318103673896002803341544124054745019340795360841685

|
|
//! * B = Fq2(0, b * NON_RESIDUE)
|
|
//! * NON_RESIDUE = 17 is the quadratic non-residue used for constructing the extension field Fq2
