Summary/Abstract: The so called “symmetric” numbers are considered in the paper and the authors study some of their various properties. Several interesting questions and problems for numbers of that kind are formulated and some concrete examples are solved. Corresponding generalizations of them are proposed. The investigation could be a base for creating many other problems, which could be used in mathematical Olympiads and competitions, as well as for the preparation for them.
