The Weyl groupoids of $\mathfrak{s}\mathfrak{l}(m\mathrm{\mid }n)$ and $\mathfrak{o}\mathfrak{s}\mathfrak{p}(r\mathrm{\mid }2n)$

We provide a convenient formulation of the definition of Cartan graphs and Weyl groupoids introduced by Heckenberger and Schneider, and construct Cartan graphs for regular symmetrizable contragredient Lie superalgebras. For $\mathfrak{s}\mathfrak{l}(m\mathrm{\mid }n)$, $\mathfrak{o}\mathfrak{s}\mathfrak{p}(2m+1\mathrm{\mid }2n)$ and $\mathfrak{o}\mathfrak{s}\mathfrak{p}(2m\mathrm{\mid }2n)$ we explicitly describe the Cartan graph in terms of partitions and determine the relations between the generators of their Weyl groupoids.
