Conjugacy classes of subgroups

#	subgroup	G/H	class size	multiplicity	normal?	properties
1	C₁₅₇	C₂	1	1	yes	maximal, characteristic, complemented, Sylow
2	C₂	—	157	1	no	maximal, Sylow

commutator, Fitting, socle, cosocle, hypocenter	C₁₅₇	C₂
LCS	G ▷ C₁₅₇
UCS	C₁

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

N	H ≅ G/N	type
1. C₁₅₇	C₂	semidirect

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