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

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