Finite Group DatabasebetaFinite Group DatabasebetaOrder 128.
198 conjugacy classes of subgroups; only the 88 normal subgroups are shown.
This group has 198 conjugacy classes of subgroups — too many to draw. Only its 88 normal subgroups are shown.
Dotted edges: containments with no intermediate normal subgroup — omitted non-normal subgroups may lie between.
