Hello, I'm Rubbish computer. An edit you recently made to Graham's number 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. Rubbish computer (Talk: Contribs) 20:15, 26 May 2019 (UTC)
