Show that G is a tree if and only if the addition of any edge to G produces exactly 1 new cycle. Definition â A graph (denoted as G = (V, E)) consists of a non-empty set of vertices or nodes V and a set of edges E.

Most of the constructed graphs have more than 1000 vertices, and the number of vertices goes up to 28431. I think I understand the construction method you have mentioned, however I cannot see how the diameter should be 2. \begin{align} Following are some regular graphs. Proof: In a complete graph of N vertices, each vertex is connected to all (N-1) remaining vertices. 1& 0& 1& 0& 0& 0& 1& 0& 0& 0& 0& 0& 0& 0& 0& 0& 0& 0& 1& 0& 1& 0\\ Another strongly regular graph with the same parameters is constructed on the codewords of the dual code.

The one on 24 vertices can be constructed with the help of twisted or star product ($K_3*X_8$), however as I see such twisted product cannot work on 22 vertices, and there are about $10^{19}$ connected 5-regular graphs on 22 vertices, so generating all of them and selecting those with diameter 2 is hopeless for me.

Save any article or search result from DeepDyve, PubMed, and Google Scholar... all in one place. Why the sum of two absolutely-continuous random variables isn't necessarily absolutely continuous? You are asking for regular graphs with 24 edges. Why should we use the fundamental definition of derivative while checking differentiability? In general, the Paley graph can be expressed as an edge-disjoint union of cycle graphs. Let $N=\{1,\dots,22\}$ be the nodes, and let $P=\{i\in N, j\in N: i
