     The other class ${\displaystyle {\mathcal {C}}_{2}}$ of loops consists of ${\displaystyle 3}$ -dimensional connected differentiable left A-loops such that the group ${\displaystyle G=PSL_{2}(\mathbb {R} )\ltimes \mathbb {R} ^{3}}$ is the group topologically generated by the left translations The loops in this class can be represented by two real parameters ${\displaystyle a,b}$ and form precisely two isomorphism classes, which coincide with the isotopism classes.
