Yes, because they are all equivalent in some way so if one is faster than the other it may be best to take advantage of that core(N)==N is asking is N the unique squarefree number dividing N ? issquarefree(N) is asking does a square divide into N ? and bigomega(N)==omega(N) are the number of primes dividing N counted with multiplicity equal to the number of distinct primes dividing N ( if so the powers on all the primes must be 1) ? norm(N) can be used in place of sqr(N) because of the way complex norms are defined they become equivalent in R.
