Presentation

minimal degree	μ(G) = 18
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 6 generators on 18 points:

(3,4,5,6)(7,8)(9,10)(12,14)(16,18);(3,4,5,6)(12,14)(15,16)(17,18);(7,8,9,10)(12,14);(1,2);(3,4,5,6)(7,8)(9,10)(11,12,13,14);(3,4)(5,6)(7,8)(9,10)

Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:

gap> G := Group((3,4,5,6)(7,8)(9,10)(12,14)(16,18), (3,4,5,6)(12,14)(15,16)(17,18), (7,8,9,10)(12,14), (1,2), (3,4,5,6)(7,8)(9,10)(11,12,13,14), (3,4)(5,6)(7,8)(9,10));
