MC: Ping-Pong Cubes

[ijabbott]

I have a list of the first 200 or so cubes that are Ping-Pong numbers if anyone is interested in seeing them. The first 10 Ping-Pong Cubes as defined by Joe are contained therein. I was curious to see if the sequence of cubes that are Ping-Pong Numbers hits a wall (or at least a very large gap) in the same way that the sequence of Ping-Pong Cubes does after the first few. It doesn't.
