Tony,
Don't know much about this stuff and the Combinatorica documentation
is far from complete, but I pieced together something that works.
Remember that the input for a HasseDiagram must be an acyclic graph,
otherwise it returns unevaluated.
ShowGraph[
HasseDiagram[
FromAdjacencyMatrix[
{
{0, 1, 1, 1},
{0, 0, 1, 1},
{0, 0, 0, 0},
{0, 0, 0, 0}
}, Type -> Directed
]
], VertexLabel -> True
]
Cheers -- Sjoerd
