1828 conjugacy classes of subgroups; only the 37 normal subgroups are shown.

normal subgroups only

This group has 1828 conjugacy classes of subgroups — too many to draw. Only its 37 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 32

A minimal faithful permutation representation — 3 generators on 20 points:

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

Polycyclic presentation:
