Presentation

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

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

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

GAP

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

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