Hello, I'm 1997kB. An edit you recently made to Petr–Douglas–Neumann theorem seemed to be a test and has been removed. If you want more practice editing, the sandbox is the best place to do so. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you. &#8208;&#8208;1997kB (talk) 05:49, 12 June 2020 (UTC)

Please refrain from making test edits to Wikipedia pages, such as the one you made with this edit to Petr–Douglas–Neumann theorem, even if you intend to fix them later. Your edits have been reverted. If you would like to experiment again, please use the sandbox. Thank you. &#8208;&#8208;1997kB (talk) 05:51, 12 June 2020 (UTC)
