100 conjugacy classes of subgroups; only the 16 normal subgroups are shown.

normal subgroups only

This group has 100 conjugacy classes of subgroups — too many to draw. Only its 16 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) = 99

A minimal faithful permutation representation — 2 generators on 20 points:

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