Ed448

Mike Hamburg’s “Goldilocks” curve $y^{2}+x^{2}=1-39081x^{2}y^{2}$

The same curve as above, showing that the sharp tips of the four-pointed throwing star are actually rounded on a microscopic scale.

Plots of the curve in untwisted Edwards normal form. Very little information on its use or recommendation. One of two curves appearing in RFC 7748, the other being Ed25519.

These quartic curves are trivially reducible to conic sections of degree two by plotting $y^{2}$ against $x^{2}$.
