Presentation

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

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

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

GAP

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

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