| #### D.5.2.44 chNumbersProj Procedure from library `chern.lib` (see chern_lib). Usage: chNumbersProj(n); n integer Return: list of integers Purpose: computes the Chern numbers of the projective space P_n Note: Example:
    LIB "chern.lib";
    ring h=0, (t), dp;
    // The Chern numbers of the projective plane P_2:
    print( chNumbersProj(2) );
    ==> [1]:
    ==>    9
    ==> [2]:
    ==>    3
    // The Chern numbers of P_3:
    print( chNumbersProj(3) );
    ==> [1]:
    ==>    64
    ==> [2]:
    ==>    24
    ==> [3]:
    ==>    4
