Conjugacy classes of subgroups

#	subgroup	G/H	class size	multiplicity	normal?	properties
1	C₂×C₈₀₈₉	C₂	1	1	yes	maximal, characteristic
2	C₈₀₈₉	C₄	1	1	yes	characteristic, complemented, Sylow
3	C₄	—	8089	1	no	maximal, Sylow

	subgroup	G/H
center, Frattini, hypercenter	C₂	D₈₀₈₉
commutator, hypocenter	C₈₀₈₉	C₄
Fitting, socle, prime radical, cosocle	C₂×C₈₀₈₉	C₂
LCS	G ▷ C₈₀₈₉
UCS	C₁ ◁ C₂

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

N	H ≅ G/N	type
2. C₈₀₈₉	C₄	semidirect

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