Are some Maple packages always loaded? example Galois Field (GF)?
Nasser M. Abbasi
Maple 12.
when I do ?index[packages], one the packages listed is Galois Field (GF)
but if I do with(GaloisField) or with(GF) I get an error that there is not
such package.
Are there such "special" packages that do not need to be loaded?
If GF is not a package, then why is it listed in the ?index[packages]
command? even though ?GF says it is a pckage.
Same problem I had with ToolboxInstaller[Data]

Technically speaking, GF is a command, so it cannot be with'ed.
But as it generates modules which in turn contain procedures,
it's quite close to a common package.
AFAIK, it has been designed this way because it provides a
computational "environment" (a finite field) where the operators
have a specific meaning.

The headline of that page is indeed a bit misleading, but the rest
of it (the Description in particular) clarifies the situation.

That's another special case: auxiliary routines for accessing
data in user-defined installers.
BTW, these cases demonstrate that accurately counting
commands is tricky. Another reason is that packages can
be nested. See particularly DifferentialGeometry, Student
(which has 6 sub-packages in Maple 13), GraphTheory, ...
I'm not going to enter that discussion in the other thread,
but if I recall correctly, Maple 7 already had ~4k commands.
