In this work we present the definition of combinatorial rank and the first examples obtained by Kharchenko and collaborators, who calculated the combinatorial rank of the positive part $u_q^+(\mathfrak{g})$ of the multi-parameter version of the Lusztig quantum group, where $q$ is a root of the unity and $\mathfrak{g}$ is a simple Lie algebra of type $A_n$, $B_n$, $C_n$ and $D_n$. As a continuation of this study, we provide the combinatorial rank for quantum groups of type $G_2$ and $F_4$.

Joint work with Bárbara Pogorelsky(Universidade Federal do Rio Grande do Sul, Brazil) and Carolina Renz(Universidade Federal de Ciências da Saúde de Porto Alegre, Brazil).
