2264 conjugacy classes of subgroups; only the 129 normal subgroups are shown.

normal subgroups only

This group has 2264 conjugacy classes of subgroups — too many to draw. Only its 129 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 19
transitive degreeμt(G) = 96

A minimal faithful permutation representation — 3 generators on 19 points:

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

Polycyclic presentation:

2^9,3|a^2=h,c^2=de,f^2=i,b^a=bf,c^a=cgi,c^b=cd,d^a=dh,d^c=dg,e^a=eh,e^b=eg,e^c=eg,f^b=fi,f^c=fhi,f^d=fi,f^e=fi,h^b=hi,j^c=j^2
