300 conjugacy classes of subgroups; only the 142 normal subgroups are shown.

normal subgroups only

This group has 300 conjugacy classes of subgroups — too many to draw. Only its 142 normal subgroups are shown.

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

minimal degree	μ(G) = 30
transitive degree	μ_t(G) = 672

A minimal faithful permutation representation — 3 generators on 30 points:

(1,2,3,4,5,6,7)(8,9,10)(15,18,20,27)(16,22,23,30)(17,24,19,26)(21,29,28,25);(15,17,20,19)(16,21,23,28)(18,26,27,24)(22,25,30,29);(9,10)(11,12,13,14)(15,16)(17,21)(18,25)(19,28)(20,23)(22,24)(26,30)(27,29)
