This group is chosen because it has large order (for large semiprime ''n''), equal to (''p''<sup>2</sup>−1)(''p''<sup>2</sup>−''p'')(''q''<sup>2</sup>−1)(''q''<sup>2</sup>−''q'').
Let <math>\chi</math> and <math>\alpha</math> be two such matrices from GL(2,''n'') chosen such that <math>\chi\alpha
:<math>\beta = \chi^{-1}\alpha^{-1}\chi,</math>
