Theorem dihpN 41301

Description: The value of isomorphism H at the fiducial atom 𝑃 is determined by the vector ⟨0, 𝑆⟩ (the zero translation ltrnid 40100 and a nonzero member of the endomorphism ring). In particular, 𝑆 can be replaced with the ring unity ( I ↾ 𝑇). (Contributed by NM, 26-Aug-2014.) (New usage is discouraged.)
