1071 conjugacy classes of subgroups; only the 47 normal subgroups are shown.

normal subgroups only

This group has 1071 conjugacy classes of subgroups — too many to draw. Only its 47 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 16
transitive degreeμt(G) = 72

A minimal faithful permutation representation — 3 generators on 16 points:

(1,4)(2,3)(5,8,7)(10,13)(11,15)(14,16);(2,4)(7,8)(9,10,11,13,12,14,15,16);(2,3,4)(6,7,8)

Polycyclic presentation:

2^4,3^2,2^4|a^2=c,c^2=d,b^a=bcd,c^b=cd,e^a=e^2,f^a=f^2,g^e=h,g^f=h,h^a=gh,h^e=gh,h^f=gh,i^a=hij,i^e=j,i^f=ghi,j^a=gj,j^e=ij,j^f=gj
