An 8-cycle is said to be squashed if we identify a pair of opposite vertices and name one of them with the other (and thereby turning the 8-cycle into a pair of 4-cycles with exactly one vertex in common). The resulting pair of 4-cycles is called a bowtie. We say that we have squashed the 8-cycle into a bowtie. Evidently an 8-cycle can be squashed into a bowtie in eight diffierent ways. The object of this paper is the construction, for every n ≥ 8, of a maximum packing of K_n with 8-cycles which can be squashed in a maximum packing of K_n with 4-cycles.

Abstract
An 8-cycle is said to be squashed if we identify a pair of opposite vertices and name one of them with the other (and thereby turning the 8-cycle into a pair of 4-cycles with exactly one vertex in common). The resulting pair of 4-cycles is called a bowtie. We say that we have squashed the 8-cycle into a bowtie. Evidently an 8-cycle can be squashed into a bowtie in eight diffierent ways. The object of this paper is the construction, for every n ≥ 8, of a maximum packing of K_n with 8-cycles which can be squashed in a maximum packing of K_n with 4-cycles.File in questo prodotto:
