Hello, I'm David Eppstein. I wanted to let you know that one or more of your recent contributions to Lai-Sang Young have been undone because they did not appear constructive. If you would like to experiment, 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. —David Eppstein (talk) 16:55, 29 May 2017 (UTC)
