Presentation

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

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

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

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