1117 conjugacy classes of subgroups; only the 43 normal subgroups are shown.

normal subgroups only

This group has 1117 conjugacy classes of subgroups — too many to draw. Only its 43 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) = 64

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

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

Polycyclic presentation:
