    "abstract": "We propose a new kind of invariant of multi-party stabilizer states with\nrespect to local Clifford equivalence. These homological invariants are\ndiscrete entities defined in terms of the entanglement a state enjoys with\nrespect to arbitrary groupings of the parties, and they may be thought of as\nreflecting entanglement in a qualitative way. We investigate basic properties\nof the invariants and link them with known results on the extraction of GHZ\nstates.",
