Query: The flag f-vectors of Gorenstein* order complexes of dimension 3   We characterize the cd-indices of Gorenstein* posets of rank 5, equivalently
the flag f-vectors of Gorenstein* order complexes of dimension 3. As a
corollary, we characterize the f-vectors of Gorenstein* order complexes in
dimensions 3 and 4. This characterization rise a speculated intimate connection
between the f-vectors of flag homology spheres and the f-vectors of Gorenstein*
order complexes.
