 ==== Graphical representation on one line ====
-We can represent elements $p\in\Part(k)$, that is, partitions of a set $\{1,\dots,k\}$ as diagrams as follows. Put $k$ points on one line representing the elements of the set $\{1,\dots,k\}$. For each block $V\in p$ connect all the points representing elements of $V$ by a node.
+We can represent elements $p\in\Pscr(k)$, that is, partitions of a set $\{1,\dots,k\}$ as diagrams as follows. Put $k$ points on one line representing the elements of the set $\{1,\dots,k\}$. For each block $V\in p$ connect all the points representing elements of $V$ by a node.
 For example, consider $k=8$ and a partition $p=\{\{1,2,5\},\{3,6\},\{4\},\{7,8\}\}$. This can be represented by the following diagram
