288 conjugacy classes of subgroups; only the 20 normal subgroups are shown.

normal subgroups only

This group has 288 conjugacy classes of subgroups — too many to draw. Only its 20 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) = 63

A minimal faithful permutation representation — 2 generators on 16 points:

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