I explicitly construct a strong zero mode in the XYZ chain or, equivalently,Majorana wires coupled via a four-fermion interaction. The strong zero mode isan operator that pairs states in different symmetry sectors, resulting inidentical spectra up to exponentially small finite-size corrections. Suchpairing occurs in the Ising/Majorana fermion chain and possibly inparafermionic systems and strongly disordered many-body localized phases. Theproof here shows that the strong zero mode occurs in a clean interactingsystem, and that it possesses some remarkable structure -- despite being arather elaborate operator, it squares to the identity. Eigenstate phasetransitions separate regions with different types of pairing.
