48 conjugacy classes of subgroups.
| subgroup | G/H | |
|---|---|---|
| center | C2×C7×C27 | C22 |
| commutator | C2 | C22×C7×C27 |
| Frattini, cosocle | C2×C9 | C22×C3×C7 |
| socle, prime radical | C2×C3×C7 | C22×C9 |
| LCS | G ▷ C2 ▷ C1 | |
| UCS | C1 ◁ C2×C7×C27 ◁ G | |
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 5. Q8×C27 | C7 | direct (N × H) |
| 6. C7×C27 | Q8 | direct (N × H) |
| 13. C7×Q8 | C27 | direct (N × H) |
| 18. C27 | C7×Q8 | direct (N × H) |
| 25. Q8 | C7×C27 | direct (N × H) |
| 26. C7 | Q8×C27 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
