Presentation

minimal degree	μ(G) = 100
transitive degree	μ_t(G) = 29792

A minimal faithful permutation representation — 2 generators on 100 points:

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", "h");;
