Presentation

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

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

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

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

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