When t = 1, we simply say that the family is intersecting. Consider the following example. Fix a t-set, say I ⊆ [n], and values {xi : i ∈ I}. If for every σ ∈ F and i ∈ I σ(i) = xi, then F is clearly t-intersecting. Furthermore, we say that F is a trivial t-intersecting family of permutations. Note that the size of this family is at most (n − t)!. Ellis, Friedgut, and Pilpel [5] show that for n...

Let us write DF (G) = {F ∈ F : F ∩ G = ∅} for a set G and a family F . Then a family F of sets is said to be (≤ l)-almost intersecting (l-almost intersecting) if for any F ∈ F we have |DF (F )| ≤ l (|DF (F )| = l). In this paper we investigate the problem of finding the maximum size of an (≤ l)almost intersecting (l-almost intersecting) family F . AMS Subject Classification: 05D05
