Hi all, now i will say something, that might be not good, in the eye of some of you. And other´s will see the light.
You don´t need quantum computering, or similar stuff to get the private key, if you have the public key.
It´s all pure math, and it´s all thinking out of the BOX, arulbero, NotATether, WanderingPhilospher and albertobsd have done so much research, that help me understand things.
I am not on the position now, to say shure it work all, but i will give you a brain tip ....
Think of 4 OCTAGON´s as a square, in public key math, you have 16 points that have no contact with something.
Maybe now you see, why dividing may not be a problem.
