- page 108, proof of Thm. 8.2: Line -8 redundand ")". Also,
the use of $r$ as the length of a longest antichain for both
$P$ and $P'$ is a bit confusing (Ronald de Wolf)

Also, here we mean permutations
*without fixed points*, i.e. derrangements (Esfandiar Haghverdi) - page 111, 1-2 lines before Sect. 8.3: In this (simplified) argument, the length $L$ is twice larger than stated: $m^2$ many blocks $\overline{D_i} C_j$ both of length at most $k$ yields $2km^2$. To get rid of this factor of 2, Lipski (1978) used a bit more subtler argument (Markus Hartmair)

- page 169: In Thm 12.7 (and in its proof), $Z_v$ stands, of course, for
the

- page 283, proof of Thm. 19.4: Strongly speaking, the event $A_v$ must be conditioned on the event $E$ that each of $r$ colors are used (Jose Falkner).

Fortunately, the conditioning will not effect much the given upper bound on $\mathrm{Pr}[A_v]$, because $\mathrm{Pr}[\neg E]\leq r(1-1/r)^n \leq r\mathrm{e}^{-n/r}$ is small enough. - page 284, line 4: replace "Since this set ..." by "Since the set $\{A_u\colon N(u)\cap N(v)\neq\emptyset\}$ ..." (Peter Stahlecker)
- page 286, Thm. 19.7: $r$ should be the ceiling of $k/\log k$, not the floor (Brent McKain)
