800 conjugacy classes of subgroups; only the 154 normal subgroups are shown.

normal subgroups only

This group has 800 conjugacy classes of subgroups — too many to draw. Only its 154 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:

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