A note on strong Skolem starters

Combinatorics 2019-07-11 v2

Abstract

In 1991, Shalaby conjectured that any additive group Zn\mathbb{Z}_n, where n1n\equiv1 or 3 (mod 8) and n11n \geq11, admits a strong Skolem starter and constructed these starters of all admissible orders 11n5711\leq n\leq57. Only finitely many strong Skolem starters have been known. Recently, in [O. Ogandzhanyants, M. Kondratieva and N. Shalaby, \emph{Strong Skolem Starters}, J. Combin. Des. {\bf 27} (2018), no. 1, 5--21] was given an infinite families of them. In this note, an infinite family of strong Skolem starters for Zn\mathbb{Z}_n, where n3n\equiv3 mod 8 is a prime integer, is presented.
