MC: Ping-Pong Cubes

[Jim Horn]

Hello, Valentin,

I just want to thank you not only for the fine work and documentation you supplied for this problem but for the many you have graced this forum with through the years. Your insight and explanations have been understandable, enlightening and enjoyable. As someone who reads them all, I seldom respond and never considered that you may feel you are casting your efforts into the void. Please be sure that you are not. I am certain that like me, many of the forum members read and appreciate your hard work without commenting.

Best to you always!

Jim Horn (Older than Joe)
