Presentation

minimal degreeμ(G) = 22
transitive degreeμt(G) = 64

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

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

GAP

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

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