Fair point. I was processing an offline database which only has the sequence number and the entries. I can't remember offhand whether it's possible to download one which has the keywords in order to identify triangles and process them specially. If not, I could look at trying to break sequences into triangles and maybe deal with a few false positives. I suppose it might also be worth trying to do the same with potential tabl sequences given by anti-diagonals.
