268 conjugacy classes of subgroups; only the 118 normal subgroups are shown.

normal subgroups only

This group has 268 conjugacy classes of subgroups — too many to draw. Only its 118 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) = 1344

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

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