Presentation

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

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

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

GAP

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

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