5526 conjugacy classes of subgroups; only the 80 normal subgroups are shown.

normal subgroups only

This group has 5526 conjugacy classes of subgroups — too many to draw. Only its 80 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 18
transitive degreeμt(G) = 80

A minimal faithful permutation representation — 3 generators on 18 points:

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