This seems like a noobish question but, with the secp256k1 curve, what is the formula for calculating the Galois field?
The bitcoin wiki gives the parameters for the curve, but I haven't been able to find a formula for how the parameters interact.
Any extra reading materials would also be helpful.
Not sure exactly what you are asking here. First of all the points on the elliptical curve for a
group, not a field.
Here is a pretty good primer on the defined addition operation for the
group.
