Draw the group operation tables for the groups ( 4, + 4 ) and ( * 5
Question:
Draw the group operation tables for the groups (ℤ4, + 4) and (ℤ*5, ·5). Show that these groups are isomorphic by exhibiting a one-to-one correspondence α between their elements such that a + b ≡ c (mod 4) if and only if α(a) · α (b) · α(c) (mod 5).
