Presentation

minimal degreeμ(G) = 68
transitive degreeμt(G) = 60900

A minimal faithful permutation representation — 2 generators on 68 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", "g");;
