This is a construction problem I fiddled with a couple of years back. (If you only want problems that improve your go skill, feel free to skip this one.)

The question is, how many living groups will fit on the 19x19 board given the following restrictions:

1. All groups have to be "alive with points", stones in seki are not allowed
2. It must be impossible to connect any two groups into one

The answer given here is not the final word on the issue, it just happens to be the best solution I was able to find. If you find a better solution, and I invite you to try, please publish it on Sensei's Library, for example.
