Presentation

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

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

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

GAP

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

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