Conjugacy classes of subgroups

#	subgroup	G/H	class size	multiplicity	normal?	properties
1	C₄×C₁₇	C₂	1	1	yes	maximal, characteristic
2	C₂×C₁₇	C₄	1	1	yes	characteristic
3	C₁₇	C₈	1	1	yes	characteristic, complemented, Sylow
4	C₈	—	17	1	no	maximal, Sylow

	subgroup	G/H
center, Frattini, hypercenter	C₄	D₁₇
commutator, hypocenter	C₁₇	C₈
Fitting, cosocle	C₄×C₁₇	C₂
socle, prime radical	C₂×C₁₇	C₄
LCS	G ▷ C₁₇
UCS	C₁ ◁ C₄

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

N	H ≅ G/N	type
3. C₁₇	C₈	semidirect

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