1694 conjugacy classes of subgroups; only the 75 normal subgroups are shown.

normal subgroups only

This group has 1694 conjugacy classes of subgroups — too many to draw. Only its 75 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:

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

Polycyclic presentation:

2^10|a^2=e,b^2=e,c^2=h,d^2=h,f^2=j,g^2=j,c^a=cd,c^b=cdfj,d^b=dg,d^c=dh,e^c=eh,f^a=fgi,f^b=fgij,f^c=fi,f^d=fi,f^e=fj,g^b=gj,g^c=gi,g^f=gj,h^b=hj,i^b=ij
