Bonse's inequality
Introduction In number theory, '''Bonse's inequality''', named after H. Bonse, relates the size of a primorial to the smallest prime that does not appear in its prime factorization. It states that if ''p''1, ..., ''p''''n'', ''p''''n''+1 are the smallest ''n'' + 1 prime numbers and ''n'' ≥ 4, then: (the middle product is short-hand for the primorial  of ''p''''n'')Mathematician Denis Hanson showed an upper bound where .
