Does the following graph:

(with graph6 string `FFzvO`

) have a name or belong to a special class?

The DIMACS (bliss) format of it is:

```
p edge 7 14
e 1 4
e 1 5
e 1 6
e 1 7
e 2 4
e 2 5
e 2 6
e 2 7
e 3 4
e 3 5
e 3 6
e 3 7
e 4 6
e 5 7
```

And another image, obtained after a permutation of vertices, is:
