Presentation

minimal degreeμ(G) = 22
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 6 generators on 22 points:

(3,4)(5,6)(7,8,9,10)(11,12)(13,14)(15,16,18,19)(17,21,22,20);(3,4,5,6)(7,8,9,10)(11,12)(13,14)(16,19)(17,22);(3,4)(5,6)(8,10)(11,12,13,14)(17,22)(20,21);(7,8)(9,10)(11,12)(13,14)(15,17)(16,20)(18,22)(19,21);(3,4)(5,6)(7,8)(9,10)(15,16)(17,20)(18,19)(21,22);(1,2)

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)(11,12)(13,14)(15,16,18,19)(17,21,22,20), (3,4,5,6)(7,8,9,10)(11,12)(13,14)(16,19)(17,22), (3,4)(5,6)(8,10)(11,12,13,14)(17,22)(20,21), (7,8)(9,10)(11,12)(13,14)(15,17)(16,20)(18,22)(19,21), (3,4)(5,6)(7,8)(9,10)(15,16)(17,20)(18,19)(21,22), (1,2));
