This invariant arises from the study of finite subgroups of maximal arithmetic kleinian groups. It measures the distance between orders $\mathcal \{D\}(a, b)$ and $\mathcal \{D\}(c, d)$ in $B$ associated to $\lbrace a, b\rbrace $ and $\lbrace c,d\rbrace .$ If $a = c$, we compute $\rho _R ([\mathcal \{D\}(a, b)], [\mathcal \{D\}(c, d)])$ by means of arithmetic in the field $k (\sqrt\{a\}).$ The problem of extending this algorithm to the general case leads to studying a finite graph associated to different Hilbert symbols for $B$.

AB - Let $B$ be a quaternion algebra over a number field $k$. To a pair of Hilbert symbols $\lbrace a, b\rbrace $ and $\lbrace c, d\rbrace $ for $B$ we associate an invariant $\rho = \rho _R \left([\mathcal {D}(a, b)], [\mathcal {D}(c, d)]\right)$ in a quotient of the narrow ideal class group of $k$. This invariant arises from the study of finite subgroups of maximal arithmetic kleinian groups. It measures the distance between orders $\mathcal {D}(a, b)$ and $\mathcal {D}(c, d)$ in $B$ associated to $\lbrace a, b\rbrace $ and $\lbrace c,d\rbrace .$ If $a = c$, we compute $\rho _R ([\mathcal {D}(a, b)], [\mathcal {D}(c, d)])$ by means of arithmetic in the field $k (\sqrt{a}).$ The problem of extending this algorithm to the general case leads to studying a finite graph associated to different Hilbert symbols for $B$. An example arising from the determination of the smallest arithmetic hyperbolic $3$-manifold is discussed.
