Do you mean find a math realation between these numbers?
first x: c994b69768832bcbff5e9ab39ae8d1d3763bbf1e531bed98fe51de5ee84f50fb
second x: 79be667ef9dcbbac55a06295ce870b07029bfcdb2dce28d959f2815b16f81798 private base x
third x: bcace2e99da01887ab0102b696902325872844067f15e98da7bba04400b88fcb
even y: 483ada7726a3c4655da4fbfc0e1108a8fd17b448a68554199c47d08ffb10d4b8 small range y private key: 1
odd y: b7c52588d95c3b9aa25b0403f1eef75702e84bb7597aabe663b82f6f04ef2777 big range y private key: fffffffffffffffffffffffffffffffebaaedce6af48a03bbfd25e8cd0364140
Like the a math realation bettewn first x and the second x?
It's called an endomorphism and the 3 X-points can all be accessible by a cube (1/3) root, a 2:3 root, and the original X:
Now multiply 2*3 combos (endomorphisms) and you get a total of 6 endomorphisms: (x,y), (y,x) (y, n-x) and (x,n-y), (n-y, x), (n-y, n-x).
There's also python code in another thread I recently saw that computes those X's from a single Y (and vice versa).
