Group #21719 — subgroups

Subgroups — C₄×#498 #21719

Order 256.

439 conjugacy classes of subgroups; only the 231 normal subgroups are shown.

normal subgroups only

This group has 439 conjugacy classes of subgroups — too many to draw. Only its 231 normal subgroups are shown.

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