minimal degree	μ(G) = 98
transitive degree	μ_t(G) = 28576

A minimal faithful permutation representation — 2 generators on 98 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", "h");;
gap> coll := SingleCollector(F, [2, 2, 2, 2, 2, 2, 19, 47]);;
