1000 conjugacy classes of subgroups; only the 258 normal subgroups are shown.

normal subgroups only

This group has 1000 conjugacy classes of subgroups — too many to draw. Only its 258 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) = 256

A minimal faithful permutation representation — 4 generators on 28 points:

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