On the nonexistence of almost Moore digraphs with self-repeats

Arnau Messegué, Josep Maria Miret

An almost Moore digraph is a diregular digraph of degree $d > 1$ , diameter $k > 1$ and order $d + d^{2} + \dots + d^{k}$ . Their existence has only been shown for $k = 2$ . It has also been conje…

A general method to find the spectrum and eigenspaces of the $k$ -token of a cycle, and 2-token through continuous fractions

M. A. Reyes, C. Dalfó, M. A. Fiol +1

The $k$ -token graph $F_{k} (G)$ of a graph $G$ is the graph whose vertices are the $k$ -subsets of vertices from $G$ , two of which being adjacent whenever their symmetric difference is…
