4 conjugacy classes of subgroups.

Conjugacy classes of subgroups

#	subgroup	G/H	class size	multiplicity	normal?	properties
1	C₈₃₉	C₃₁	1	1	yes	maximal, characteristic, direct product factor, Sylow
2	C₃₁	C₈₃₉	1	1	yes	maximal, characteristic, direct product factor, Sylow

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

N	H ≅ G/N	type
1. C₈₃₉	C₃₁	direct (N × H)
2. C₃₁	C₈₃₉	direct (N × H)

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