* Rework bw6-761 to bw6-767

use bls12-381 instead of 377 for test imports

fix the inline comments with correct name and params


Set the right base field


Equation for base curve is y2 = x3 + 1


fill in pairing params


adapt sage scripts with correct moduli


calculate the correct cubic non residue


correct the parameter B in the curve equation


remove the specialized method for mult by nonresidue

nonresidue is two, so default will be doubling

calculate more correct parameters for fq3

`TRACE_MINUS_ONE_DIV_TWO` and `QUADRATIC_NONRESIDUE_TO_T`

compute the right fq3 & fp6 frobenious coefficients


calculate the cofactor for g1


use the g1 generator from gnark's fork


use the right g2 equation


g2 cofactor is slightly smaller than g1 cofactor


get the g2 generators from gnark's fork


update g1 and g2 curve info in the comments


fill in `COFACTOR_INV` value for g1


fill in `COFACTOR_INV` value for g2

* update module description

author information
2-adicity of the scalar field

* update changelog

* remove trailing comma

* remove todo

* 2nd loop count is x^3 - x^2 - x

* Revert "2nd loop count is x^3 - x^2 - x"

This reverts commit 2b323db3ba.

* fix comment regarding non-residue

* first loop count should be X

* 1. Generic BW6 params added to BW6-761
2. Curve specific hard part of the final exp moved from algebra

* 1. Generic BW6 params added to BW6-767
2. Miller loop params changed to the "unoptimized" version

* cargo fmt

* changelog updated

* X_MINUS_1_DIV_3 added to BW6Config

* imports fixed
