Presentation

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

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

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

GAP

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

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