On Some Classes of Functions and Hypercubes
  In this paper, some classes of discrete functions of $k$-valued logic are considered, that depend on sets of their variables in a particular way. Obtained results allow to "construct" these functions and to present them in their tabular, analytical or matrix form, that is, as hypercubes, and in particular Latin hypercubes. Results connected with identifying of variables of some classes of functions are obtained.
