1668 conjugacy classes of subgroups; only the 32 normal subgroups are shown.

normal subgroups only

This group has 1668 conjugacy classes of subgroups — too many to draw. Only its 32 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 — 2 generators on 24 points:

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

Polycyclic presentation:

2^4,3,2^5|b^2=j,c^2=d,f^2=j,g^2=j,b^a=bc,c^a=cd,c^b=cd,e^a=e^2,f^a=fghj,f^e=g,g^a=gi,g^e=fgj,g^f=gj,h^a=hi,h^e=hi,h^f=hj,h^g=hj,i^e=h,i^f=ij
