A reformulation of the generalized $q$-Painlevé VI system with $W(A^{(1)}_{2n+1})$ symmetry

Abstract: In the previous work we introduced the higher order $q$-Painlev\'{e} system $q$-$P_{(n+1,n+1)}$ as a generalization of the Jimbo-Sakai's $q$-Painlev\'{e} VI equation. It is derived from a $q$-analogue of the Drinfeld-Sokolov hierarchy of type $A^{(1)}_{2n+1}$ and admits a particular solution in terms of the Heine's $q$-hypergeometric function ${}{n+1}\phi_n$. However the obtained system is insufficient as a generalization of $q$-$P{\rm{VI}}$ due to some reasons. In this article we rewrite the system $q$-$P_{(n+1,n+1)}$ to a more suitable one.
