23736 conjugacy classes of subgroups; only the 160 normal subgroups are shown.

normal subgroups only

This group has 23736 conjugacy classes of subgroups — too many to draw. Only its 160 normal subgroups are shown.

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

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

A minimal faithful permutation representation — 3 generators on 16 points:

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