3970 conjugacy classes of subgroups; only the 269 normal subgroups are shown.

normal subgroups only

This group has 3970 conjugacy classes of subgroups — too many to draw. Only its 269 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 162

A minimal faithful permutation representation — 4 generators on 24 points:

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

Polycyclic presentation:

2,3^7|c^3=d^2,e^3=h,c^a=ch^2,c^b=cd,e^a=e^2h^2,e^b=eh^2,f^a=f^2,g^a=g^2,h^a=h^2
