WebJul 20, 2024 · A clique is a collection of vertices in an undirected graph G such that every two different vertices in the clique are nearby, implying that the induced subgraph is complete. Cliques are a fundamental topic in graph theory and are employed in many other mathematical problems and graph creations.

WebIf you double the last digit and subtract it from the rest of the number and the answer is: 0, or divisible by 7 then the number itself is divisible by 7. Example: 672 (Double 2 is 4, 67-4=63, and 63÷7=9) Yes. 905 (Double 5 is 10, 90-10=80, and 80÷7=11 3/7) No. If the number is too big you can repeat until you find the solution. In the mathematical area of graph theory, a clique is a subset of vertices of an undirected graph such that every two distinct vertices in the clique are adjacent. That is, a clique of a graph is an induced subgraph of that is complete. Cliques are one of the basic concepts of graph theory and are used in many other mathematical problems and constructions on graphs. Cliques have also been …
WebJust in case, let us remind you that a clique in a non-directed graph is a subset of the vertices of a graph, such that any two vertices of this subset are connected by an edge. In particular, an empty set of vertexes and a set consisting of a single vertex, are cliques. WebMay 21, 2024 · The clique number is $5$. Note that there can be at most one even number in a clique, as two even numbers would have a common factor of $2$. Also note that $3$ and $9$ cannot be in the same clique as $3$ divides both. So not all odd numbers can be used. This gives us a maximum bound of $5$ numbers in a clique.
