The documents linked here set out topics that might be interesting for a Circle to consider. The point of the documents is to mention an interesting question and show, by way of example, that there are interesting things one might say about it. In many cases the approach taken and/or results obtained grew out of what our Circle in Cincinnati came up with. In many cases, too, I've gotten carried away and played more with the question just because I had so much fun with it at our Circle.

Most of the documents below are part of a work in progress call Math Play.
