180 conjugacy classes of subgroups; only the 87 normal subgroups are shown.

normal subgroups only

This group has 180 conjugacy classes of subgroups — too many to draw. Only its 87 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) = 720

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

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