Abstract
The circulant Gβ=βC(n,S), where $S\subseteq Z_n\setminus{0}$, is the graph with vertex set Z~n~ and edge set $E(G)= {{x,x+s}|x \in Z_n,s \in S}$. It is shown that for n odd, every 6βregular connected circulant C(n, S) is decomposable into Hamilton cycles. Β© 2006 Wiley Periodicals, Inc. J Combin Designs

We show any flow in any connected circulant graph of odd order can be expressed as a sum of Hamilton cycles.
Select four perfect matchings of 2n vertices, independently at random. We find the asymptotic probability that each of the first and second matchings forms a Hamilton cycle with each of the third and fourth. This is generalised to embrace any fixed number of perfect matchings, where a prescribed set
