Presentation

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

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

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

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

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