Presentation

minimal degree	μ(G) = 97
transitive degree	μ_t(G) = 26999

A minimal faithful permutation representation — 2 generators on 97 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");;

gap> SetPower(coll, 2, F.5);;
