##
## This simple structure is used by many of the nightly Zoltan tests.
## It can be interpreted as a mesh, a graph, a hypergraph, or simply
## as 25 objects to be partitioned.

##  Regarded as a hypergraph, we associate each of the 25 objects with a
##  hyperedge.  The hyperedge is composed of the object and its neighbors
##  in the above structure.  For example, hyperedge 1 contains vertices
##  1, 2 and 6.  Hyperedge 13 contains vertices 13, 8, 12, 14 and 18.

##  Number of vertices:
25

##  Here we list the global ID of each vertex.

##  Here we list for each hyperedge, its global ID, the number of vertices it links,
##  and the global ID of each vertex in the hyperedge.
