Presentation

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

A minimal faithful permutation representation — 7 generators on 18 points:

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

GAP

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

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