Major update: with coauthor @YoussefElHousn3 we generalized the previous result to more family of curves like BLS/BN/KSS (finding a general solution to the diophantine equation) and we also showcase 2 new curves

Posted on eprint a modest paper (Family of embedded curves for BLS) preview basically shows how to build embedded curves (ร  la JubJub/Bandersnatch) having GLV endomorphism (ร  la Bandersnatch) providing general formulas derived from the BLS curveโ€™s seed.
