Hello, I'm Pizzaplayer219. An edit that you recently made to Triangular number seemed to be a test and has been reverted. If you want to practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks! Pizzaplayer219TalkContribs 12:29, 14 October 2022 (UTC)
