The work has come to a halt again. I'd like additional hints. Let's see whether Proxima and Clam barge in and don't want hints. :-)
Complete list of koans are in my latest post before this one.
Current ideas: Anything < 3 letters is black. Some letters allow same-letter koans, others don't. The allowed length varies highly. The status is independent of anagramming.
I have shoved the
koans through a number-crunching script, but didn't see any pattern. The script converts letters into numbers, sorts, and adds them.
