2033 conjugacy classes of subgroups; only the 75 normal subgroups are shown.

normal subgroups only

This group has 2033 conjugacy classes of subgroups — too many to draw. Only its 75 normal subgroups are shown.

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

Presentation

minimal degreeμ(G) = 19
transitive degreeμt(G) = 48

A minimal faithful permutation representation — 3 generators on 19 points:

(2,3)(5,9)(6,15,7,12,13,14)(10,18,11)(16,19,17);(1,2,3)(4,15,8,13)(5,18,9,19)(6,7,12,14)(10,17,16,11);(4,5,8,9)(6,10,12,16)(7,11,14,17)(13,18,15,19)

Polycyclic presentation:
