The polynomial is 1296*x^24 - 20736*x^22 + 129600*x^20 - 393984*x^18 + 
584496*x^16 - 362880*x^14 + 62208*x^12  

- Can SAGE find the gcd of a polynomial and its derivative? 


 polygen(QQ)    #What doe this do? What is QQ# ? 
p = 1296*x^24 - 20736*x^22 + 129600*x^20 - 393984*x^18 + 584496*x^16 - 
362880*x^14 + 62208*x 
for (q,n) in p.squarefree_decomposition(): 
     print q.degree(), n, gp.polsturm(q) 


Can someone explain what are these q.degree, n and gp.plotsum ?
