The monodromy group of a truncated simplex

Open problems on k-orbit polytopes

“…4.12]. Describing the monodromy group of several families of polytopes is an active area of research; see [2,3,33,56,68].…”

“…When both P and Q are chiral, the universal amalgamation is in fact rooted. For example, the universal amalgamation of {4, 4} (1,3) with {4, 4} (1,3) has 24 vertices, whereas the universal amalgamation of {4, 4} (3,1) with {4, 4} (1,3) has 50 vertices [9].…”
