“…More specifically, we shall make use of the following two constructions. For similar applications of this technique, the reader is referred to [4,5,6,15,16,18] In the construction of GDDs or PBDs, the technique of ''filling in holes'' plays an important role. This simple technique also works effectively for the construction of a variety of other combinatorial structures (see, for example, [5]).…”

“…It is known [14] that the spectrum of SPSs is precisely the set of all n ≡ 1 or 5 (mod 10), except n = 15, for which no such system exists. SPSs are also known to be useful in the construction of other types of designs such as perfect Mendelsohn designs with block-size five (see [4]). …”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
