## L dimension may be chosen within each of the subspaces L in the set S that are ''in general position.'' For example, in the real projective space of dimension 3, consider a plane , a line r not belonging to , the point P [ r l , and two distinct points Q, R both different from P, lying on the l

We call a partially ordered set A sharply transitive if its group of order automorphisms is sharply transitive on A, that is, if it is transitive on A and every non-trivial automorphism has no fixed points. We show that the direct product of any finite group with an infinite cyclic group is the auto

The closed cone of flag vectors of Eulerian partially ordered sets is studied. A new family of linear inequalities valid for Eulerian flag vectors is given. Half-Eulerian posets are defined. Certain limit posets of Billera and Hetyei are half-Eulerian; they give rise to extreme rays of the cone for
