maxima a lot as my preferred CAS calculator because sinse I have no vision, the
normal calculators are of no use to me as there is no accessible interface that
I can use. I have a question relating to combinatorics: is it possible to do
permutations in maxima? I can do them in my head, but when there are a lot of
numbers, this can get tricky. So is there a function I can use for NCR or NPR?
If so, this would also save a lot of typing so that I don?t have to manually do
so much multiplication.

Sure there is:
permutation(n,r);
for example: permutation(6,2);
to use it, you need to load(functs) first.
good luck with your study.
