Hello,
there is a long-standing problem with the package gf:
The documentation says that gf_exp(p,n) can be used for "integer power",
but for example n=-1 seems always to run into an infinite loop, so
for example using the example from the documentation:
gf_exp(x^3+x,-1);
And actually, every negative power seems to run into an infinite loop,
for example:
gf_exp(x^3+x,-14);
By the way, the documentation following that example says:
Primitive elements, powers and logarithms
The non-zero elements of a finite field form a multiplicative group; a
generator of this group is a
primitive element of the field.
What is a "multiplicative group"? I guess what is meant is that the
non-zero elements under multiplication form a *cyclic group*.
Greetings
Oliver
