Line 2384 the Groebner basis check and ideal-membership check ar

Line 2393 the Groebner basis check and ideal-membership check ar

In this case, an automatically chosen prime if @code{p} is 1,

otherwise the specified prime is used to compute a Groebner basis

candidate.

Execution of @code{nd_f4_trace} is done as follows:

For each total degree, an F4-reduction of S-polynomials over a finite field

is done, and S-polynomials which give non-zero basis elements are gathered.

Then F4-reduction over Q is done for the gathered S-polynomials.

The obtained polynomial set is a Groebner basis candidate and the same

check procedure as in the case of @code{nd_gr_trace} is done.

@item

@code{nd_f4} executes F4 algorithm over a finite field.

@code{nd_f4} executes F4 algorithm over Q if @code{modular} is equal to 0,

or over a finite field GF(@code{modular})

if @code{modular} is a prime number of machine size (<2^29).

@item

@code{nd_weyl_gr}, @code{nd_weyl_gr_trace} are for Weyl algebra computation.
