Hi, all

I tried by:

>alias(a=RoofOf(z^4+z+1)):

> if a > 2 then print('yes') end if;
Error, cannot determine if this expression is true or false: 2 < RootOf(_Z^4+_Z+1)
 

Any ideas?

 

Thank you.

Hi, all,

 I checked all the information of Groebner Basis in maple, and I cannot find how to compute Groeber Basis over Galois Field, for example how to computer Groebner Basis over GF(2^4)?

 

Thank you.

I cannot believe it.

HI, all,

I found a weird problem:

When I used the subsop separately, it work fine. But when it was put in a procedure, then it cannot work. So weird!

For example:

>L:=[x,y,z,d];

                            L:=[x,y,z,d]

>L:=subsop(1=NULL,L);
