Let $D_n$ be the finite Coxeter group of type $D_n$. A minuscule middle order is a middle order arising from the minuscule construction described in the paper. Type D minuscule cla…

Let $B_n$ be the type $B$ finite Coxeter group, with $n\geq3$, and let $J$ be a maximal parabolic subgroup. A middle order is a distributive lattice that refines the weak order and…
