I solved this one along with the other magic square caches a while ago. I worked on it for quite a while and had something that appeared to follow the pattern extrapolated from the smaller squares. The only problem was that my square wasn't quite magic. After scratching my head for a long time and rechecking my work, I decided to try another method. I found some code that calculated magic squares, ported it to Java, had my solution and finally understood the pattern.
The cache was right where I expected to be in this nice park. Thanks.
