Quaternary mention?

I not only didn't see any mention of non-communal "quaternary marriages" mentioned in this article, I couldn't find a single mention anywhere on wikipedia. Could quaternary marriages be mentioned or even have its own article? I learned about it earlier today in the letter section of Popular Science and this was basically the only worthwhile web reference I could find outside of discussion about group marriages: [1] — Preceding unsigned comment added by 4.254.115.130 (talk) 03:51, 14 June 2007 (UTC)[reply]

Types and Zygosity section

I removed table added in 2016 by Gatorgirl7563. It contained no information not already found in article. Tables should help the reader correlate related facts, however out of 77 cells, 66 were "X" (which was not defined). 2 columns were completely "X", so served no purpose. I am assuming that Gatorgirl7563 thought that it would be expanded and clarified by other editors over time, but at only 14% filled in, took up a lot of space without adding clarification to the article. There were previous discussions on talk page to remove or improve. If someone wanted to create a comprehensive table that correlates all aspects of the different types of twinning, I would support that, but it should add information to the article by showing how their attributes compare and contrast. • Bobsd • (talk) 17:13, 7 July 2024 (UTC)[reply]
