Hi. I just realized that in your sequences related to the shell model of partitions (A135010...) you refer to an infinite ordering of finite integer partitions that is probably the same I have defined in A194602. It is easily seen that your illustration of the partitions of 10 equals mine. At the moment I don't get your definition of this order. Do you see whether our definitions are the same or not?

Excuse me, I would like to ask for any other reference about Spiral of Triangles around a Hexagon Juan M. Marquez 02:24, 9 November 2012 (UTC) Juan M. Marquez

Outer shell

I made the requested change: outer shell of the partitions to last section of the set of partitions. But there are still 45 instances of "outer shell" not using the exact wording you used; these will probably need to be changed by hand.

Thank you for the changes! I just added a new request in the suggested projects page. Omar E. Pol 13:29, 1 December 2013 (UTC)

Non-Mersenne primes

You might be amused that I added a reference to your sequence A138837 at Template:Sequences in the News since it was on Wired (and some traditional papers) recently. The connection is a bit tenuous, I'll admit, but we do what we can...!

Thank you very much!

Description of A160790

I have trouble understanding the description of A160790: Vertex number of a rectangular spiral.

In my understanding, this is a rectangular spiral with 12 vertices:

 *-*-*-*
 |     |
 * *-* *
 |   | |
 *-*-* *

(With my understanding, all the possible vertex numbers would be given by A002620 - Quarter squares.)

So apparently I misunderstood something. Could you please clarify? Christian Sievers 11:55, 13 March 2014 (UTC)

Recommended reading about formulae?

You commented my draft A257637, stating that the "formula section needs work". Now, this is my first proposed new series, and I'm not surprised to hear that I should do things differently; but I don't understand how. I read both Style Sheet#Formula and Style Sheet#Spelling and notation and tried to follow the recommendations there; and I reread them now, and also looked at a few other formula sections; and I just don't see what I've done wrong. Could you please give me a tip, or a suggested reading link? Jörgen Backelin 08:47, 5 November 2015 (UTC)

Jörgen: please see the history 12 in the pink box of A257637.
