fromFVector -- If possible, returns a simplicial poset with the given f-vector.

Synopsis

Usage:

P = fromFVector(L)
Inputs:
- L, a list, The desired F-vector.
Outputs:
- P, an instance of the type Poset, A simplicial poset with f-vector L.

This method is provided as a way to construct an example of a simplicial poset with a given f-vector.

It implements a construction due to Richard Stanley.

For details about this construction and a description of what f-vectors can be constructed, see Stanley's original paper.

i1 : P = fromFVector({1,6,5,1});

i2 : isSimplicial(P)

o2 = true

i3 : getFVector(P)

o3 = {1, 6, 5, 1}

o3 : List
