4547 conjugacy classes of subgroups; only the 142 normal subgroups are shown.

normal subgroups only

This group has 4547 conjugacy classes of subgroups — too many to draw. Only its 142 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 21
transitive degreeμt(G) = 72

A minimal faithful permutation representation — 3 generators on 21 points:

(1,2,4)(10,12)(13,21,16,15,14,18,19,17,20);(2,3)(6,8)(9,10)(11,12)(14,16)(15,19)(17,20)(18,21);(5,6)(7,8)

Polycyclic presentation:
