Abstract: | Latin square type partial difference sets (PDS) are known to exist in R × R for various abelian p‐groups R and in ?t . We construct a family of Latin square type PDS in ?t × ?2ntp using finite commutative chain rings. When t is odd, the ambient group of the PDS is not covered by any previous construction. © 2002 Wiley Periodicals, Inc.
