Symmetric Group on 3 Letters/Group Presentation

Group Example
The group presentation of the symmetry group of the equilateral triangle is given by:
 * $D_3 := \left \langle{a, b: a^3 = b^2 = \left({a b}\right)^2 = e}\right\rangle$

Hence:
 * $\begin{array}{c|cccccc}

& e & a & a^2 & b & a b & a^2 b \\ \hline e & e & a & a^2 & b & a b & a^2 b \\ a & a & a^2 & e & a b & a^2 b & b \\ a^2 & a^2 & e & a & a^2 b & b & a b \\ b & b & a^2 b & a b & e & a^2 & a \\ a b & a b & b & a^2 b & a & e & a^2 \\ a^2 b & a^2 b & a b & b & a^2 & a & e \\ \end{array}$
