Question
Suppose v1,..., Vk are linearly independent vectors in
R" (1 <k < n). Then the set Xk = conv{±v1,...,±v }
is called a k-crosspolytope.
a. Sketch X' and X².
b. Determine the number of k-faces of the 3-dimensional
crosspolytope X³ for k = 0, 1,2. What is another name
for X3?
c. Determine the number of k-faces of the 4-dimensional
crosspolytope X* for k = 0,1,2, 3. Verify that your
%3D
answer satisfies Euler's formula.
d. Find a formula for fi (X"), the number of k-faces of X",
for 0 <k <n – 1.
