708 conjugacy classes of subgroups; only the 84 normal subgroups are shown.

normal subgroups only

This group has 708 conjugacy classes of subgroups — too many to draw. Only its 84 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 15
transitive degreeμt(G) = 56

A minimal faithful permutation representation — 3 generators on 15 points:

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