13504 conjugacy classes of subgroups; only the 252 normal subgroups are shown.

normal subgroups only

This group has 13504 conjugacy classes of subgroups — too many to draw. Only its 252 normal subgroups are shown.

Dotted edges: containments with no intermediate normal subgroup — omitted non-normal subgroups may lie between.

Presentation

minimal degreeμ(G) = 18
transitive degreeμt(G) = 54

A minimal faithful permutation representation — 3 generators on 18 points:

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

Conjugacy classes & character table

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

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