Presentation

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

A minimal faithful permutation representation — 7 generators on 22 points:

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

GAP

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

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