minimal degree	μ(G) = 160
transitive degree	μ_t(G) = 34544

A minimal faithful permutation representation — 2 generators on 160 points:

GAP

Past the SmallGroups library coverage — no SmallGroups id. Construct it from its polycyclic presentation:

gap> F := FreeGroup(IsSyllableWordsFamily, "a", "b", "c", "d", "e", "f");;
