Presentation

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

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

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

GAP

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

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