330 conjugacy classes of subgroups; only the 102 normal subgroups are shown.

normal subgroups only

This group has 330 conjugacy classes of subgroups — too many to draw. Only its 102 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 29
transitive degreeμt(G) = 320

A minimal faithful permutation representation — 3 generators on 29 points:

(1,2,3,4,5)(6,7,10,11,9,13,8,12)(14,15,19,20,18,23,17,22)(16,24,26,21,25,28,27,29);(15,20)(16,25)(17,19)(21,24)(22,23)(28,29);(7,11)(8,10)(12,13)(14,16,17,26,18,25,19,27)(15,21,22,28,23,29,20,24)
