Presentation

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

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

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

GAP

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