Some types of problems from probability theory

In the article, we discussed the structure of the space of elementary motions of the discrete type in the problem of placing n particles in the partition M. We deal with such problems in statistical physics, when studying the distribution of n particles (these can be protons, neutrons or other particles) in M ​​states (these can be energy levels). We have considered several tasks of different types and have calculated all the sesaslo elementary movement quantities.
