For any 4-regular graph G (possibly with multiple edges), we prove that, if the number N of distinct Euler orientations of G is such that N β‘ 1 (mod 3), then G has a 3-regular subgraph. It gives the new 4-regular graphs with multiple edges which have no 3-regular subgraphs, for which we know the num

Let β« be a distance-regular graph with l (1 , a 1 , b 1 ) Ο 1 and c s Ο© 1 Ο 1 for some positive integer s . We show the existence of a certain distance-regular graph of diameter s , containing given two vertices at distance s , as a subgraph in β« .
Let β« be a distance-regular graph with a 1 ΟΎ 0 , r Ο max Ν j 3 ( c j , a j , b j ) Ο ( c 1 , a 1 , b 1 ) Ν Ρ 2 and a i Ο a 1 c i , for 1 Ρ i Ρ 2 r . Take any u and in β« at distance r Ο© 1 . We show that there exists a collinearity graph of a generalized 2( r Ο© 1)-gon of order ( a 1 Ο© 1 , c r Ο© 1 Οͺ 1)
In this paper we give a sufficient condition for the existence of a strongly closed subgraph which is (c q + a q )-regular of diameter q containing a given pair of vertices at distance q in a distance-regular graph. Moreover we show that a distance-regular graph with r = max{ j | (c j , a j , b j )
We present two extensions of a theorem by Alon and Yuster (1992, Graphs Comb., 8, 95-102) that give degree conditions guaranteeing an almost-spanning subgraph isomorphic to a given graph. The first extension gives a sharp degree condition when the desired subgraph consists of small connected compone
