Basic Group Theory: Cayley Tables for ℤ1, ℤ2, ℤ3, and ℤ4 (as well as Abstract Group Versions)

   • Abstract Algebra  . In basic group theory, we make Cayley tables for ℤ1, ℤ2, ℤ3, and ℤ4 (also isomorphic abstract versions for ℤ1, ℤ2, ℤ3, and a non-isomorphic, non-cyclic abstract group with 4 elements, called the Klein four-group). We discuss identities and inverses (both additive and multiplicative inverses).    • Abstract Algebra Course, Lecture 1: Introd...  .
