Presentation

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

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

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

GAP

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

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