%0 Journal Article %T Periodicity related to a sieve method of producing primes %A Haifeng Xu %A Zuyi Zhang %A Jiuru Zhou %J Mathematics %D 2014 %I arXiv %X In this paper we consider a slightly different sieve method from Eratosthenes' to get primes. We find the periodicity and mirror symmetry of the pattern. %U http://arxiv.org/abs/1406.0429v6
