Group #1641 — subgroups

Subgroups — #1641

Order 128.

125 conjugacy classes of subgroups; only the 36 normal subgroups are shown.

normal subgroups only

This group has 125 conjugacy classes of subgroups — too many to draw. Only its 36 normal subgroups are shown.

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