It doesn't help that the first example (6, 28, 496) are also all perfect numbers, which no explanation given.  —Preceding unsigned comment added by CallipygianSchoolGirl (talk • contribs) 05:16, 14 April 2008 (UTC)

replies: text: What about ? (6, 28) is the smallest and simplest example, but not typical since the kinship is an integer. I pointed that out and made the smallest non-integer example later. PrimeHunter (talk) 22:35, 14 April 2008 (UTC)
thread_title:  Lead Paragraph 

message: I see the "popular culture" section of this article has been removed without saying why.  Although I have no vested interest in it one way or the other, I liked the pun.  Of course, if removing the section improves this article, then I'm all for it.  But the article doesn't seem any better now, without that section.  Was the topic simply not notable?—GraemeMcRaetalk 16:01, 12 March 2009 (UTC)
thread_title:  Removal of "imaginary friends" pun 

message: It was recently added that 10 has no friend < 2,000,000,000.  According to , 10 and some others have no friend < 10^30.  Bubba73 You talkin' to me? 02:55, 22 December 2017 (UTC)
thread_title:  Solitary numbers - 10, etc 

message: It looks like "friendly numbers" in common core are numbers that end in 5 and 0. I don't have a great reference for this other than this math lesson on YouTube, https://www.youtube.com/watch?v=G-79q7wk5ag.  Parents may find this article and get even more confused because they're looking for the arithmetic definition. --TIB (talk) 02:25, 9 November 2023 (UTC)
thread_title:  Friendly numbers in basic arithmetic 

message: Citation [4] on this page leads to a ResearchGate writeup of a submission to the IOSR Journal of mathematics (a predatory / pay-to-play publisher)
https://www.researchgate.net/publication/373980593_The_Form_of_The_Friendly_Number_of_10
Clicking through, we see that the author of this submission is one Sourav Mandal of Ramakrishna Mission Vivekananda University
Previously, this citation pointed directly to the IOSR Journal, but was rolled back because IOSR is not a reliable source. Checking the history of this Wikipedia article, you can see that both the original citation and the replacement were made by the IP address 14.139.215.81, which resolves directly to Vivekananda Educational & Research Institute West Bengal.
For this reason, I believe that Mr. Mandal has been editing this page with his own article in order to boost his mathematical reputation.
What's worse, however, is that if you read his journal submission linked above, it's almost a one-for-one plagiarism of a 2006 undergraduate project from Clarkson University in the US:
https://lin-web.clarkson.edu/projects/cosi/fa2006/students/wardjm/lonenumber.pdf
I claim that Mr. Mandal plagiarized a 17 year old college project, submitted it to a scam journal, laundered the scam journal's link through the aggregator ResearchGate, and is personally seeding this Wikipedia page with references to his "work" for personal gain. 96.230.33.41 (talk) 16:28, 28 November 2023 (UTC)
