Hi, and welcome to Wikipedia. Can you explain why you think it's a good idea to replace the standard "=" symbol by the symbol "≡" on Pappus chain? It seems unconstructive and counterproductive to me, and you've now been reverted twice by two different editors (with me as one of them). Rather than continuing to make the same change and continuing to get reverted, how about we have a discussion and you try to persuade the other editors that this is an improvement? —David Eppstein (talk) 04:55, 12 July 2015 (UTC)
