I was using this website
https://asecuritysite.com/ecc/ecc_points_multI was putting random p-prime numbers, then "manually"

bruteforce X value to get valid point
Then if you get rule (n-1)mod 6 = 0 then you basically got the smaller version of standard secp256k1 - you will get the sets of 2 Y values with 3 X values just like in regular curve
The smalles example is p = 7 G=(1, 1)
P (1,1) Point is on curve
2P (2,1) Point is on curve
3P (4,6) Point is on curve
4P (4,1) Point is on curve
5P (2,6) Point is on curve
6P (1,6) Point is on curve
7P=0
