The University of Michigan Combinatorics Seminar
In this talk I will define the packing density of a permutation, a pattern
or a word. The packing density measures how many times a given word can
occur in a word of given (large) length. I will present results by Price,
by Albert, Atkinson, Handley, Holton & Stromquist, as well as by
Burstein, Mansour and myself (which, to the best of my knowledge, exhaust
what is known about packing density).
