Every wiki sequence page could be a redirect page

Every wiki sequence page could be a redirect page to the sequence page; this would allow to rebuild all the sequences categorizations in the wiki, hopefully from the backup of the former wiki sequence pages. I made the test page A000001 (note that the redirect is not automatic, though.)

The wiki sequence pages could be in edit draft mode to make sure that they contain only a redirect to and categories.

Yes, I think we should consider this. It's been a lot of work to fix all the wikilinks in my workspaces that got deleted in the changeover. Jon Awbrey 15:22, 3 January 2011 (UTC)

Items to be deleted by Editors

Since I am not an Associate Editor, I cannot delete any OEIS Wiki pages. But to facilitate the maintenance of the wiki by the Editors, I created quite some time ago the template Template:Discarded which requests for the deletion of the item (page, category, ...) and automatically categorizes the item in Category:Discarded items for convenience. — Daniel Forgues 05:01, 14 February 2011 (UTC)

{{BASEPAGENAME}} and {{SUBPAGENAME}} magic words in Template namespace

The {{BASEPAGENAME}} and {{SUBPAGENAME}} magic words currently don't work properly in the Template namespace. (see the {{test}} template) It think the $wgNamespacesWithSubpages wiki global variable is currently set to its default value (which doesn't enable subpages in the Template namespace)

The {{BASEPAGENAME}} and {{SUBPAGENAME}} magic words only work in namespaces that have subpages enabled. See Manual:$ for information on enabling subpages.

The {{documentation subpage}} template currently doesn't work in the Template namespace because of this issue. — Daniel Forgues 01:11, 16 August 2011 (UTC)

The problem has been fixed long ago. — Daniel Forgues 03:46, 28 February 2013 (UTC)

Dear N. J. A. Sloane

Dear Professor I received a warning from you containing some point.

I have respected these points and ensure you I will respect them strictly.
However it was strange that the warning was written and sent (he said on your behalf, and that he wrote it for you) by the Editor Charles R Greathouse IV with whom I have an actual Editorial Conflict.
Please can you clear this to my modest person.
PS. You can see the conflict summary <edited before your warning> here .

Open problem (Invitation):

Given an integer N>0, and after been found all the first N! terms of A217626, you were asked find either a function or algorithm which counts the number of different "trivial" palindromic patterns that could be built from these terms.

For example:

[1,9,2,9,1] is a "trivial" palindromic pattern.


[2,18,4,18,2] is not trivial, until it is re-written it as: [2,2*9,4,9*2,2]

So the "triviality" of such kind of patterns depends on the prime factorization of their components. Such behavior can not be reproduced by the prime numbers.

I can not spot it yet "the how", but the study of this matter might have deep implications in the number theory. (These patterns teach us how to build odd numbers in a similar way as what described by the Goldbach's Conjecture for the even numbers).

If you decide to face this friendly challenge,

Good Luck!!!

Sincerely, with regards:

Tooltips with sequence names in OEIS Wiki

I implemented a demo (for up to A000999) of tooltips with sequence names (in the wiki) with the {{sequence}} template. The thing is, for 200000 sequences, it takes 200 tables (1000 sequences per table)... (Starting with we use slices of 1000 sequence names, then some editing is required.) Also, if we want to use it, we would have to ask Russ Cox to modify the script concerning the A-numbers to invoke the template.

For example

{{sequence|A000795}} or {{seq|A000795}} (for short)

Thank you, etc.

Thanks for recently moving along one of my sequences.

As you may know, I have long ago been restricted to 3 sequences in edit at one time and have had difficulty getting certain things done here as a result, with sporadic and unpredictable internet time to devote to OEIS. I'm not sure you can do much about this or would want to, but I do wish to ask that editors who have been involved in editing my sequences be observed in this process. In particular, the current 3 sequences in edit seem indisputably of interest as base-type sequences, and a multi-editor assault on them does indeed seem to have started.

The situation here is somewhat reminiscent of my activity with a lesser mathematics site where numerous submissions were published and then removed from edit with a claim that the site had been hacked. I'm not sure nor could I reasonably guess what the root cause of the problem there or here at OEIS is, but it is likely that in delaying to ask your assistance I have done myself some disservice. If you cannot or do not wish to involve yourself, I appreciate the space here to make the request in any case.James G. Merickel 16:01, 29 August 2013 (UTC)

Dead links to Coordination Sequences document

There are currently 512 sequences whose description refers to which appears to be no longer available (404 not found). Since I found no explicit “report an error” link on the page of the sequences, and since that list is rather large, I'm using this talk page here as a means of reporting the problem. If this should be inappropriate, and you'd prefer I write to Mr. Grosse-Kunstleve, please let me know. Since I could not even find a recent home page of him, that might be tricky, and editing that many posts manually will be a pain, so I hope you have something more automatic to deal with this issue. — Martin von Gagern 21:59, 2 January 2014 (UTC)

(I'm not Dr. Sloane, but I'll comment if you don't mind.)
Note that the Internet Archive has a copy of the site [1] so there is at least some chance of recovering it. It would be great if you could contact Dr. Grosse-Kunstleve -- perhaps there is a newer version, or a more stable link -- but in a pinch we could link to the archived version.
It may be possible to automatically fix most or all of the references, but it would be best to first find out the best place to which to link.

I have a copy of the lost html file. It needs updating, but I plan to do that ASAP, I will upload it to the OEIS, and change all the links to point to it. Jan 03 2014: this has now been fixed. - Neil Sloane
