How exactly x^2 is = x^3+7? Is that a typo? Also have you ever seen x=y in secp256k1?
A few months ago as I was playing around with xs and ys, I remember to see something like x=y, but since I had no  clue what that could really mean, I just ignored it.

Main question, what would be the result of finding such points on secp256k1?
