2996 conjugacy classes of subgroups; only the 61 normal subgroups are shown.

normal subgroups only

This group has 2996 conjugacy classes of subgroups — too many to draw. Only its 61 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) = 16

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

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

Polycyclic presentation:

2^10|a^2=e,e^2=g,b^a=bg,c^a=cd,d^a=df,d^b=dij,e^c=ef,e^d=eh,f^a=fh,f^e=fi,g^c=gi,g^d=gj,h^a=hi,h^e=hj,i^a=ij
