Hello, I'm Wtmitchell. An edit you recently made to Chain complex 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. Wtmitchell (talk) (earlier Boracay Bill) 17:09, 22 October 2020 (UTC)
