Abstract
A theorem of Erdös says: If A is a family of subsets of a set S of n elements and no h + 1 different members of the family form a chain A1 ⊂ ... ⊂ An+1, then the maximum of the size of A is the sum of the h largest binomial coefficients of order n. The paper gives a weaker condition guaranteeing the same maximum. It is formulated in more abstract language. © 1972.
