On a graph isomorphic to $N O^{+} (6, 2)$

Federico Romaniello, Valentino Smaldore

Let $Q^{+} (2 n - 1, 2)$ be a non-degenerate hyperbolic quadric of $P G (2 n - 1, 2)$ . Let $N O^{+} (2 n, 2)$ be the tangent graph, whose vertices are the points of $PG(2n-1,2) \setminus Q^{+}(2n…

A construction for a counterexample to the pseudo 2-factor isomorphic graph conjecture

M. Abreu, M. Funk, D. Labbate +1

A graph $G$ admiting a $2$ -factor is \textit{pseudo $2$ -factor isomorphic} if the parity of the number of cycles in all its $2$ -factors is the same. In [M. Abreu, A.A. Diwan, B. Ja…
