The words in the title are characterized by the fact that a smaller number must (first) appear earlier than a larger number, and that all numbers 1,..., k are present (for some k). Under the ...

To an extended generalized permutohedron we associate the weighted integer points enumerator, whose principal specialization is the f-polynomial. In the case of poset cones it refines Gessel’s ...
