1587 conjugacy classes of subgroups; only the 39 normal subgroups are shown.

normal subgroups only

This group has 1587 conjugacy classes of subgroups — too many to draw. Only its 39 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:

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

Polycyclic presentation:
