## JSON code of the network

{"nodes":["r","a","b","c","d","e","f","1","2","3","4"],"edges": [["r","a"],["a","1"],["a","b"],["b","c"],["c","2"],["b","d"],["d","3"],["r","e"],["e","c"],["e","f"],["f","d"],["f","4"]]}

## Visualization of the network

*r* is the root and the leaves are labeled from 1 to 4.
Arcs are oriented from the parent to the child.

## Classes containing this network or not

### Classes which contain this network (with direct proof)

- binary level-2: Easy to check.
- binary distinct-cluster: All vertices correspond to distinct clusters if hybrid vertices are contracted with their tree vertex child: c(1)={1}, c(2 contracted with c)={2}, c(3 contracted with d)={3}, c(4)={4}, c(r)={1,2,3,4}, c(a)={1,2,3}, c(b)={2,3}, c(e)={2,3,4}, c(f)={3,4}.
- binary spread-1: Consider the order 1 2 3 4 of the leaves to obtain spread 1.

### Classes which do not contain this network (with direct proof)

- binary regular: c(b)={2,3} is contained in c(e)={2,3,4}, however there is no path from e to b.
- binary leaf outerplanar: Easy to check.
- binary 1-reticulated: Both vertices c and d can be reached by 2 internally-vertex-disjoint paths from r (one containing a and the other one containing e).

### All classes

In the inclusion diagram below, the names of classes containing this network are colored green and the name of the classes not containing it are colored red.
