3465 conjugacy classes of subgroups; only the 122 normal subgroups are shown.

normal subgroups only

This group has 3465 conjugacy classes of subgroups — too many to draw. Only its 122 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 16
transitive degreeμt(G) = 48

A minimal faithful permutation representation — 4 generators on 16 points:

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