Hi,

I want to choose from the following list of polynomials ( list s ),

a: =FactorList[Factor[x^63-1, Modulus\[Rule]2]]
t :=Table[a[[i,1]],{i,Length[a]}]
s :=Union[Flatten[
Table[

PolynomialMod[(x+1)*
t[]^x3 t[[ 4]]^x4   t[]^x5 t[[ 6]]^x6  t[]^x7  t[[ 8]]^
x8  t[]^x9  t[[ 10]]^x10 t[]^x11  t[[ 12]]^x12 t[]^
x13  t[[ 14]]^x14,2] ,{x3,0,1}, {x4 ,0,1},{x5,0,1}, {x6 ,0,
1},{x7,0,1}, {x8 ,0,1},{x9,0,1}, {x10 ,0,1},{x11,0,1}, {x12 ,0,
1},{x13,0,1}, {x14 ,0,1}]]
]
polynomials of degree greater than 31.

I wrote these these 2 functions but none of these work.

----------------------------------------------------------------------------
----------

1. Using Recursion on list

v={};w=1;
If[Exponent[s[[w]],x]>31,Append[v, {}],Append[v, s[[w]]]];
v

---------------------------------------------------------------------------
------------------------

2. Using While

v={};w=1;
While[Exponent[s[[w]],x]>31,v=Append[v, s[[w]]]; i++ ];
v

----------------------------------------------------------------------------
---------------------

Does anybody have an idea to do this?

Thanks a lot for your help
