#### D.15.3.42 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
