{{Alertbox|pink|For future readers: This task was renamed from "Anti-Primes Plus" and split into multiple tasks. Any reference to anti-primes plus is a remnant from before the rename.}}
== OEIS A069654 ==
the first 25 are:
Line 28 ⟶ 29:
:::::::: Perhaps we should have two tasks: A005179 Smallest number with exactly n divisors; and A069654 a(1) = 1; for n > 1, a(n) = smallest number > a(n-1) having exactly n divisors. <br> If we can only have one I would favour A005179 for its number theoretic interest. Why does the sequence have spikes at prime n? Anyone proposing this task should be able to answer this question!!!! --[[User:Nigel Galloway|Nigel Galloway]] ([[User talk:Nigel Galloway|talk]]) 16:20, 10 April 2019 (UTC)
::::::::: Already said in [[Anti-primes_Plus#Pascal|Pascal]]. waitung for CalmoSoft :-) -- [[User:Horsth|Horsth]]
:::::::::: I'm sure that why the sequence has spikes at prime n hasn't been adequately said! I've now had my say at http://www.rosettacode.org/wiki/Talk:Sequence:_smallest_number_with_exactly_n_divisors.
== Rename and split ==
This task is worthwhile but extremely poorly named and specified. The task has almost nothing to do with anti-primes other than it uses divisors. There is no other use of the term "anti-primes plus" that Google, Bing or Duckduckgo can find anywhere on the web so the name is suspect at best, and it doesn't really capture what the task is supposed to do. [[User:Calmosoft]] (the original author) doesn't speak English as his first language so demanding that he come up with a better name / description may be futile.
I propose to rename this task and add two other tasks. Since most people (including the original author) seemed to interpret this task as [[oeis:A069654|OEIS:A069654]], this task will become that. (smallest number of examples that will need to be moved/modified)
:*(this task) Sequence: smallest number greater than previous term with exactly n divisors ([[oeis:A069654|OEIS:A069654]])
:*(new task) Sequence: smallest number with exactly n divisors ([[oeis:A005179|OEIS:A005179]])
:*(new task) Sequence: nth number with exactly n divisors ([[oeis:A073916|OEIS:A073916]])
if you have a suggestion for a better/shorter name for any of these that is descriptive enough to be able to tell essentially what the task is asking for, please share it. --[[User:Thundergnat|Thundergnat]] ([[User talk:Thundergnat|talk]]) 15:16, 11 April 2019 (UTC)
