This is a basic question but I just don't understand it as of yet. In the given scenario, how do I find the values of G,q given g = 5?

1. El Gamal Let G be the group of quadratic residues mod 23 (Recall that quadratic residues are values :6 E G at. Ely E g for which a: = 33). (a) Show an execution of Gen when we choose 9 : 52 : 2 mod 23 and 319 = 4
