Abstract

By definition a group is a nonempty set G and a map
$$G \times G \mathrel\backepsilon \{ x,y\} \mapsto xy \in G$$
subject to the following axioms:
  1. i

    If x, y, zG then x(yz) = (xy)z (associativity)

     
  2. ii
    There is in G an element denoted e with two properties:
    1. iia

      if xG then ex = x (e is a left identity);

       
    2. iib

      if xG there is in G a left inverse y such that yx = e
