Presentation

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

A minimal faithful permutation representation — 8 generators on 22 points:

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

Conjugacy classes & character table

640 conjugacy classes. The character table is too large to display.

GAP

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

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