1603 conjugacy classes of subgroups; only the 185 normal subgroups are shown.

normal subgroups only

This group has 1603 conjugacy classes of subgroups — too many to draw. Only its 185 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 27
transitive degreeμt(G) = 162

A minimal faithful permutation representation — 3 generators on 27 points:

(1,5,9,3,8,4,6,2,7)(11,16,18,13,14,17)(12,15);(10,11,13)(12,14,17)(15,18,16)(20,23,24)(22,26,27);(11,14,18)(13,16,17)(19,20,22)(21,24,26)(23,27,25)

Polycyclic presentation:

2,3^7|d^3=e,c^b=cf,g^a=g^2,g^b=gh,g^d=gh,h^a=h^2
