On the Number of SDR of a (t, n)-family

European Journal of Combinatorics, 1989
A system of distinct representatives of a family \({\mathcal F}=A_ 1,...,A_ n)\) is a sequence \((a_ 1,...,a_ n)\) of distinct elements with always \(a_ i\) in \(A_ i\). Write N(\({\mathcal F})\) for the number of different such systems for the family \({\mathcal F}\). The family \({\mathcal F}\) is said to be a (t,n)-family if \(| \cup \{A_ i;i\in I\}|
