Hi
Using Maple V, Release 4.
Is there a method in the GF package, or in the GF mode in Domains, which
gives the discrete logarithm of a value?
Currently I do this by constructing a table of powers of a primitive
root, and then inverting the table to get the logarithms. But these
tables rapidly outgrow Maple's capacity ("Object too large"), and I do
not see a method of giving Maple more memory.
Strictly speaking, all I need to know is whether the logarithm is odd or
even, but a general answer would also be useful.
Thanks in advance for any assistance.
