The elliptic curve group of an elliptic curve is a group in which the elements of the group are points on an elliptic curve.

The group operation is called elliptic curve point addition.

And when it can't, attempt to classify which subset of the integers can be reached. E.g. Legendre's three-square theorem.

Compared to Waring's problem, this is potentially much harder, as we can go infinitely negative in our attempts, there isn't a bound on how many tries we can have for each number.

In other words, it is unlikely to have a Conjecture reduction to a halting problem.

A theorem that is not very important on its own, often an intermediate step to proving something that the author feels deserves the name "theorem".
