Presentation

minimal degreeμ(G) = 18
transitive degreeμt(G) = 256

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

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

GAP

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

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