Problems in programming| Zusammenfassung: | Lists use for representation of various knowledge. As lists it comfortably to present formulas, functions, trees, columns, great numbers and many other difficult objects. Great number - one of the most essential structures of data, used both in mathematics, and in programming. The formalization of lists, list-based predicates and set-based predicates in the meta-language of normal forms of knowledge is presented, based on the known Prolog-formalizations of these concepts, which use a list-domain. Among the described list-based predicates are the following: adding an element to the list, removing an element, finding the last element of a list, finding adjacent elements in a list, concatenation of lists, reversing a list, palindrome, etc. Using the list-domain, the set-based predicates are described as follows: converting a list into a set, checking if an element is in a set, concatenation, intersection, difference, symmetrical difference, identity, complement of sets, relation of subset, proper subset.
