4641 conjugacy classes of subgroups; only the 177 normal subgroups are shown.

normal subgroups only

This group has 4641 conjugacy classes of subgroups — too many to draw. Only its 177 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) = 64

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

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

Polycyclic presentation:

2^10|a^2=e,b^2=d,e^2=j,f^2=i,b^a=bf,c^a=cj,d^a=dg,e^b=egh,e^d=ej,f^a=fghi,f^b=fgi,f^d=fi,g^a=gj,g^b=gi,h^a=hj,h^b=hij
