What is clique? According to the classical definition, clique is a community of closely related people that are cohesive, have a common goal or activity. In some cases the community can be secret.

Nowadays, with the development of mathematics and social networks clique is defined in a different way. It is a group of people having the maximal count in which every pair have a relation. In fact, searching for such clique is a NP-complete problem in general case. This means at the moment there is no fast algorithm that is capable of solving it. Inventing of such algorithm (or proving that it does not exist) would solve the P vs NP millennium problem.

Nevertheless the clique problem can be solved in some particular cases, for example for friends of a given VK user. That is what this page is about. Entering a certain VK user you are able to find out what is the clique he belongs to.
