We start from the following question:
What is the maximal number of subsets of a given finite set such that no one subset is covered by t others?
We present the history of this problem which was discovered under different names in group testing, coding theory and combinatorics. We consider variations of the problem, in particular, Renyi-Ulam search with a lie. Then we embed the problem into more general question:
How to find unknown subset of a finite set?

Everyone is invited to attend. The language of the lecture is English. The event is aimed at master and graduate students, as well as researchers in the field of combinatorics.
