[Haskell-cafe] NumberTheory library

Hi I've been running Hugs for a couple of weeks now and I'm slowly starting to get the Haskell idea, and I certanly like it! But there are functions that I cant find and that I assume others before me must have missed and then perhaps also implemented them. Is there any standard library with functions like: binomial isCatalan nthCatalan nextCatalan isPrime nthPrime nextPrime factorize isFibonacci nthFibonacci nextFibonacci and possibly/hopefully other essential functions as well? (and of course better naming...) /Bo
