Presentation

minimal degreeμ(G) = 22
transitive degreeμt(G) = 256

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

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

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

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