TLDR
In this article, the authors consider some elementary applications along the lines described by S.R. Hall at the 1970 Advanced Study Institute on Direct and Patterson Methods at Parma, and propose a general method of incorporating space group symmetry into crystallographic programs.Abstract:
Structure factor algebra (Bertaut, 1956) provides a general method of incorporating space group symmetry into crystallographic programs. We shall consider some elementary applications, along the lines described by S.R. Hall at the 1970 Advanced Study Institute on Direct and Patterson Methods at Parma.read more

TL;DR: In this paper, a proposal for a standardized presentation of inorganic crystal-structure data with the aim to recognize identical or nearly identical structures from the similarity of the numerical values of the atom coordinates is presented.
