 Hello,

 I see that the documentation for grid_graph at
 http://www.boost.org/doc/libs/1_49_0/libs/graph/doc/grid_graph.html says
 that the number of dimensions should be greater than 2, but I can't really
 see why is that important while looking at the source code, and the test
 passes even for 1 dimension.

 But it is clear that a dimension length must be greater than 2 if the
 dimension is wrapped, as in the opposite case (length=2) it is impossible
 to distinguish between wrapping and non-wrapping edge.

 Maybe the documentation being intended to specify the lower limit for a
 dimension length rather than a dimensionality and requires a fix?
