Presentation

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

A minimal faithful permutation representation — 6 generators on 22 points:

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

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

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