11//! This library implements the MNT6_298 curve generated in
12//! [[BCTV14]](https://eprint.iacr.org/2014/595).  The name denotes that it is a
13//! Miyaji--Nakabayashi--Takano curve of embedding degree 6, defined over a 298-bit (prime) field.
14//! The main feature of this curve is that its scalar field and base field respectively equal the
15//! base field and scalar field of MNT4_298.
16//!
17//!
18//! Curve information:
19//! * Base field: q = 475922286169261325753349249653048451545124878552823515553267735739164647307408490559963137
20//! * Scalar field: r = 475922286169261325753349249653048451545124879242694725395555128576210262817955800483758081
21//! * valuation(q - 1, 2) = 34
22//! * valuation(r - 1, 2) = 17
23//! * G1 curve equation: y^2 = x^3 + ax + b, where
24//!    * a = 11
25//!    * b = 106700080510851735677967319632585352256454251201367587890185989362936000262606668469523074
26//! * G2 curve equation: y^2 = x^3 + Ax + B, where
27//!    * A = Fq2 = (0, 0, a)
28//!    * B = Fq2(b * NON_RESIDUE, 0, 0)
29//!    * NON_RESIDUE = 5 is the cubic non-residue used to construct the field extension Fq3
