Subgroups — C₃³ #83

Order 27.

28 conjugacy classes of subgroups.

Conjugacy classes of subgroups

#	subgroup	G/H	class size	multiplicity	normal?	properties
1	C₃²	C₃	1	13	yes	maximal, direct product factor
2	C₃	C₃²	1	13	yes	direct product factor

Splittings G = N ⋊ H with N normal; H ≅ G/N.

N	H ≅ G/N	type
1. C₃²	C₃	direct (N × H)
2. C₃	C₃²	direct (N × H)

By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
