* <strong>Union</strong>: Gelly's `union()` method performs a union on the
vertex and edges sets of the input graphs. Duplicate vertices are removed from
the resulting `Graph`, while if duplicate edges exists, these will be
maintained.
+* <strong>Difference</strong>: Gelly's `difference()` method performs a
difference on the vertex and edges sets of the input graphs. Common vertices
are removed from the resulting `Graph`, along with the edges which which have
these vertices as source/target.

you have written which twice, "along with the edges which which" :)
