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

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