Thanks a lot. My version was Ubuntu 12.04. Now I can fix the problem.

Hi,
I am trying to perform ElimLin on the PRESENT polynomial system of equations
generated by present.py written by Martin Albrecht (available here:

Cremona already confirmed it is a bug, are you an ultrafinitarist

This is mentioned in http://trac.sagemath.org/ticket/13430#comment:1, but
it is later stated that this is fixed by

ticket was never applied, as the problem still exists in version 5.12.

I would say it's not a bug. The problem is that your question "does pol
have a zero near 1?" depends on what's hidden in the O(3^5).
For example: (t-1)^2 - 3^6 does have a zero near 1, but (t-1)^2 - 3^7
does not have a zero
I know of nothing built in to Sage, but this is easy to write. The following
seems to work, even if it isn't very elegant:
def factrep(nn):
n=nn
i=1
while factorial(i)<=n:
i+=1
i-=1
ans=[]
while i>0:
d=n//factorial(i)
ans.append(d)
n-=d*fact

I agree -- even I can solve (t-1)^2=0. Perhaps the code does not
correctly do an initial squarefree division?
John
This appears a bug to me:
sage: Kz.=Qp(3,5)[];pol=t**2-2*t+1;ro=pol.roots(multiplicities=0);ro
[]
sage: pol(1)
O(3^5)
