Intersection of edge sequences

```
## S3 method for class 'igraph.es'
intersection(...)
```

`...` |
The edge sequences to take the intersection of. |

They must belong to the same graph. Note that this function has ‘set’ semantics and the multiplicity of edges is lost in the result.

An edge sequence that contains edges that appear in all given sequences, each edge exactly once.
