408 conjugacy classes of subgroups; only the 64 normal subgroups are shown.

normal subgroups only

This group has 408 conjugacy classes of subgroups — too many to draw. Only its 64 normal subgroups are shown.

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

Presentation

minimal degree	μ(G) = 29
transitive degree	μ_t(G) = 320

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

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