I'm not complaining about Wikipedia here, just noting for the thread: it's a vector of polynomials. It has a nonsingular Jacobian. Provided with it are 3 distinct points it sends to the same point; it can't be invertible.

What Wikipedia says about this doesn't matter, does it?

Wikipedia does have a rule allowing "routine calculations"

Of course given the magnitude of the statement a bit of care is warranted, but the rules do allow it.

I think Wikipedia has very sane processes. I'm just saying that process isn't useful to this thread. It's like if I found a SHA2 collision. I'd probably have to be an absurdly talented (and lucky) cryptanalyst to do that, but anybody on the thread could trivially confirm my finding.
