  We discuss bosonization and Fermionic Short-Range-Entangled (FSRE) phases of
matter in one, two, and three spatial dimensions, emphasizing the physical
meaning of the cohomological parameters which label such phases and the
connection with higher-form symmetries. We propose a classification scheme for
fermionic SPT phases in three spatial dimensions with an arbitrary finite point
symmetry G. It generalizes the supercohomology of Gu and Wen. We argue that the
most general such phase can be obtained from a bosonic "shadow" by condensing
both fermionic particles and strings.
