Abstract:
In this paper, we give some decompositions of triples of $mathbb{Z}_{p^n } $ or $mathbb{Z}_{3p^n } $ into cyclic triple systems. New constructions of difference families are given. Some infinite classes of simple cyclic triple systems are obtained from these decompositions.
Keywords:Decomposition   cyclic designs   triple systems   simple designs   difference families
