Abstract Algebra 47: Introduction to Isomorphisms
Abstract: Instead of giving the rigorous definition, we first give a visual introduction to isomorphisms. We explain how one can visually see that the group U(8) of units modulo 8 (under multiplication modulo 8) is isomorphic to the Klein 4 group Z/2Z x Z/2Z.
