<caldwell@utm.edu> Iago Camboa pointed out that n!/n# (nfactorial divided by nprimorial) is the product of all the composite numbers less than or equal to n and suggested the name compositiorial. The numbers n!/n# + 1 (when prime) might be given the name compositorial prime (like factorial prime and primorial prime). For example, Daniel Heuer noted the primes of these forms with n < 10000 are Notice that 280!/280# + 1 (= 281!/281# + 1) are twin primes!
