Group #21721 — subgroups

Subgroups — C₄×#499 #21721

Order 256.

387 conjugacy classes of subgroups; only the 207 normal subgroups are shown.

normal subgroups only

This group has 387 conjugacy classes of subgroups — too many to draw. Only its 207 normal subgroups are shown.

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