3025 conjugacy classes of subgroups; only the 95 normal subgroups are shown.

normal subgroups only

This group has 3025 conjugacy classes of subgroups — too many to draw. Only its 95 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) = 32

A minimal faithful permutation representation — 3 generators on 24 points:

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

Polycyclic presentation:

2^10|a^2=hj,c^2=f,e^2=j,c^a=ce,c^b=cd,d^a=dg,d^c=di,e^b=egi,e^c=eh,e^d=ei,f^a=fhj,f^b=fi,f^e=fj,g^c=gi,h^c=hj
