Presentation

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

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

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

GAP

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

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