I see that the ticket http://trac.sagemath.org/sage_trac/ticket/4533 has been closed. Thank you for the effort, now divisors in SAGE is much faster!! However, the one that packed in SAGE 3.2 is still about 3 times slower than that in PARI. I wonder if all the improvements have been implemented

Oh really. Now I realized why I had in my mind that SAGE was much slower---the test what based on a more complicated function instead of just divisors. Looking forward to SAGE 3.2.1 then. On Nov 24, 11:05 pm, William Stein [EMAIL PROTECTED] wrote: On Mon, Nov 24, 2008 at 10:43 PM, pong [EMAIL
