Presentation

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

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

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

GAP

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

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