Presentation

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

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

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

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

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