Presentation

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

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

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

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

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