1598 conjugacy classes of subgroups; only the 278 normal subgroups are shown.

normal subgroups only

This group has 1598 conjugacy classes of subgroups — too many to draw. Only its 278 normal subgroups are shown.

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

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 4 generators on 20 points:

(2,4)(13,14)(15,19,20,17)(16,18);(5,6,8,10)(7,11,12,9)(13,14)(15,17)(16,18)(19,20);(5,7,8,12)(6,9,10,11)(13,15)(14,17)(16,20)(18,19);(1,2,3,4)

Polycyclic presentation:
