message: Could someone knowledgable in this subject please review the edit made by 165.234.104.24 on 27 March? This IP address has made a considerable number of vandalism edits on other articles, and I am reluctant to allow this edit to stand. -- Arwel (talk) 19:55, 10 April 2007 (UTC)
replies: text: Looks ok to me. The new polynomial listed as having the plastic number as a root, x^7-2x^4-1, equals (x^3-x-1)(x^4+x^2-x-1), where the desired root occurs due to the left factor. —David Eppstein 20:38, 10 April 2007 (UTC)

message: The external link, "Tales of a Neglected Number" written by Ian Stewart, from the June 1996 Scientific American, contains the line "In 1991 Steven Arno of the Supercomputing Research Center in Bowie, MD proved that Perrin pseudoprimes must have at least 15 digits."  Obviously, the statement is false, as Perrin pseudoprimes with as few as 6 digits were discovered in 1982 by William Adams and Daniel Shanks.  I recommend that the line above be removed from Wikipedia's version of Ian Stewart's article.75.165.242.83 (talk) 05:11, 8 January 2012 (UTC)

message: I notice that while the page denotes the plastic number as \rho, some of the sources denote it as P or something else. Which way should the plastic number be denoted? 50.90.50.100 (talk) 22:31, 13 May 2015 (UTC)
replies: text: I've seen it mostly denoted as \psi in the geometrical literature, and I feel tempted to replace it as such in the entire article. No identd (talk) 02:51, 8 November 2017 (UTC)

message: 'There are precisely three ways of partitioning a square into three similar rectangles'
What about splitting it into three squares, where two of the squares have a side length of zero?

thread_title:  Square dissection 

message: I've just removed this from the lead (following the first formula):
::2\rho = \frac{\sqrt[3]{12\sqrt{3}+4\sqrt{23}}+\sqrt[3]{12\sqrt{3}-4\sqrt{23}}}{\sqrt{3}}
:The second formula is interesting as in the case of an Equilateral triangle 12\sqrt{3} is the condition where the Perimeter of the triangle equals its Area.
I do not know if this formula should appear - or if there is a good source to support it. But there are several problems with the text, which need to be fixed if it is reinserted:
*interesting - weasel word
*case of - presumes a context in which an equilateral triangle is a "case", but no such context is given
*Equilateral, Perimeter, Area - idiosyncratic capitalization
*12\sqrt{3} is the condition - how is a number a condition? I suppose what is meant is that an equilateral triangle has perimeter=area if some characteristic of the triangle equals this number, but which characteristic is that? (A good guess would be that this number is the area and the perimeter, but don't leave us guessing!)
*So, the number 12\sqrt{3} shows up in a certain triangle, but what, then, about other elements in the formula such as 4\sqrt{23}, or what about the formula as a whole, or the plastic number?
*Even if the above is fixed, it may not be clear that this information is significant enough to make it into the article, let alone into the lead.

message: re "or is there an esoteric meaning of integer"? See algebraic integer. But I agree that your short description is better per WP:SDNOTDEF, because less likely to confuse readers who are just using short descriptions to disambiguate searches rather than to provide the most accurate definition in the fewest characters. —David Eppstein (talk) 06:07, 3 February 2024 (UTC)
