500 conjugacy classes of subgroups; only the 130 normal subgroups are shown.

normal subgroups only

This group has 500 conjugacy classes of subgroups — too many to draw. Only its 130 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 3 generators on 28 points:

(6,11,12,7)(13,14)(15,20,24,27)(16,19)(17,21)(18,22)(23,26,25,28);(1,2)(3,4)(5,6,9,11,10,12,8,7)(14,19,22,21)(15,23,24,25)(20,27)(26,28);(2,4)(5,7,8,6,10,11,9,12)(13,15,16,23,18,24,17,25)(14,20,21,28,22,27,19,26)
