Presentation

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

A minimal faithful permutation representation — 5 generators on 22 points:

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

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

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