fvector -- The F-vector of a complex.

Synopsis

Usage:
fvector(C)
Inputs:
- C, an embedded complex
Outputs:
- a list

Description

The fvector of C. This is printed always when printing a complex and the faces are known.

i1 : R=QQ[x_0..x_5];

i2 : C=fullCyclicPolytope(3,R);

i3 : fvector C

o3 = {1, 6, 12, 8, 1}

o3 : List

i4 : eulerCharacteristic C

o4 = 0

i5 : dC=boundaryOfPolytope(C);

i6 : fvector dC

o6 = {1, 6, 12, 8, 0}

o6 : List

i7 : eulerCharacteristic dC

o7 = 1
