Sexy primes isn't significantly different from successive primes. Rosetta code is about algorithmic expression rather than tricking programmers into not searching through highest prime plus six. Please remove the task. --LambertDW 15:16, 20 May 2019 (UTC) |

:I think the problem is with the Successive Primes task. Which primes separated by 2 are not successive? (none). Which primes separated by 4 are not successive? (only 3 and 7 with 5 playing gooseberry). Interest begins at 6 when 7 and 13 are a sexy pair but are not successive (11 playing gooseberry). So we have a sequence of sexy primes starting at 7, and a sequence of successive primes separated by 6 starting at 31 which is a subset of the sexy primes. Beyond being a subset what other relationships exist? What happens beyond 6? As it stands the Successive Primes task offers no insight into Successive Primes. I have added 2 references to that task. The first looks at the number theoretic issues, the second at some interesting questions that can be asked about Successive Primes. Another contributor has added a third reference which takes one of the questions asked in 2 (what is the longest sequence of Successive Primes with increasing separation?) to the max.--[[User:Nigel Galloway|Nigel Galloway]] ([[User talk:Nigel Galloway|talk]]) 10:26, 21 May 2019 (UTC) |

:I think both tasks should remain. Maybe this task could be better worded - it's still in draft, and now is the time to suggest/make improvements? |
