Hello, Le 2013-11-30 03:57, Alberto Zelaya a écrit : > Based on this equivalence we can draw a system of sieves for the > 6n+/-1 set up to 100. One question : why 100, is it an arbitrary value and if so, how did you choose it ? > To morrow I will continue with this explanation. Please do. > Alberto Zelaya YG

• ### study of wheel sieve algorithms

Hello list, I finally have some time off and I'm returning to my analysis of prime gaps with the angle of certain wheel sieves. The beginning is here, please have a look : http://ygdes.com/~whygee/gaps_20131126.html I'm pretty confident that this text is solid up to this point but I want to be sure it is error-free before I write more. Happy clicking ! yg

• ### Outline of a demonstration of the Twin Primes Conjecture and more

...there by studying the transformations of the wheel Wp(n) to create Wp(n+1). This is where algorithms show up. In http://ygdes.com/~whygee/srs.html I have merged my algorithmic approach with the remarks made by Steve Maddox on this list http://tech.groups.yahoo.com...

• ### Help/advices/knowledge needed about a family of patterns

Hello list, I just came across the cyclic sequence [12, 7, 4, 7, 4, 7, 12, 3] which is directly related to the well known sequence [6, 4, 2, 4, 2, 4, 6, 2] ( http://oeis.org/A145011 ) but I don't see or find the first sequence in OEIS. In the next days I'll study certain properties of this sequence and its siblings. Has anybody seen it already ? How ? why ? when ? where ? Yann...
