Presentation

minimal degreeμ(G) = 22
transitive degreeμt(G) = 512

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

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

Conjugacy classes & character table

416 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((3,4,5,6)(7,8,9,10)(11,12,13,14)(15,16)(17,18)(20,22), (4,6)(8,10)(12,14)(16,18)(19,20)(21,22), (7,8)(9,10)(16,18), (11,12)(13,14)(15,16)(17,18), (3,4)(5,6)(7,8)(9,10)(11,12)(13,14), (1,2));
