A graph has girth >=9 if it has no cycles with less than 9 vertices.
Let $X$ be a hereditary class of graphs and let $X_n$ denote the set of $n$vertex graphs in $X$. The function $X_n$ is called the speed of the class $X$.
The map shows the inclusions between the current class and a fixed set of landmark classes. Minimal/maximal is with respect to the contents of ISGCI. Only references for direct inclusions are given. Where no reference is given, check equivalent classes or use the Java application. To check relations other than inclusion (e.g. disjointness) use the Java application, as well.

Consider the following decomposition of a graph $G$ which is defined
as a pair $(T,L)$ where $T$ is a binary tree and $L$ is a bijection
from $V(G)$ to the leaves of the tree $T$. The function
$\text{cutbool} \colon 2^{V(G)} \rightarrow R$ is

V(G) \backslash A \mid \exists X \subseteq A \colon
S = (V(G) \backslash A) \cap \bigcup_{x \in X} N(x)\}$.
Every edge $e$ in $T$
partitions the vertices $V(G)$ into $\{A_e,\overline{A_e}\}$ according
to the leaves of the two connected components of $T  e$.

of $T$ to edges of $G$. Any edge $\{u, v\}$ of the tree divides
the tree into two components and
divides the set of edges of $G$ into two parts $X, E \backslash X$,
consisting of edges mapped to the leaves of each component. The
width of the edge $\{u,v\}$ is the number of vertices of $G$ that is incident both with an edge in
$X$ and with an edge in $E \backslash X$. The width of the
decomposition $(T,\chi)$ is the maximum width of its edges. The

Consider a decomposition $(T,\chi)$ of a graph $G$ where $T$
is a binary tree with $V(G)$ leaves and $\chi$ is a
