The structure of four-torsion points
Over the algebraic closure, secp256k1 has 16 points killed by multiplication by four, forming a group isomorphic to (Z/4Z)².
- Why it is useful
- Connects explicit curve calculations to a finite group structure that later formal work can reuse.
- Scope
- This is the concrete n = 4 case, not a theorem for every n or a discrete-logarithm algorithm.
