Presentation

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

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

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

GAP

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

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