I am preparing teaching materials and have come across your package. Thank you. It seems to work fine and I am delighted that the guide systematically gives the cross links to OEIS.
Here are some minor points as I use the different functions:
a) The default for many sequences is gmp=TRUE. Could you also have that for Fibonacci - where it is currently FALSE.
b) Your description for Deficient mistakenly says abundant: Under OEIS A005100, a deficient number is a number whose proper divisors sum up to the extent smaller than the number itself. First 6 abundant numbers are 1, 2, 3, 4, 5, 7
c) Your example for Double Factorial should presumably use Factorial.Double? Currently it is:

 ## generate first 10 odd Factorials
print(Factorial(10))

d) I wonder if there should be a warning for Perfect - and perhaps some others - that they only work easily for small n? I found Perfect(10) is fine, but even Perfect(15) takes quite a time. Perhaps Force = FALSE as default when n > limit?
