Presentation

minimal degreeμ(G) = 22
transitive degreeμt(G) = 128

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

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

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

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