228 conjugacy classes of subgroups; only the 126 normal subgroups are shown.

normal subgroups only

This group has 228 conjugacy classes of subgroups — too many to draw. Only its 126 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 30
transitive degreeμt(G) = 672

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

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