I guess, you are missing the 4 vs. 1 TBs like KQQQK. I think, they will be of
extremely limited use. Some programs will probe 4 vs. 1 TBs, others won't. If I
count correctly from Eugene Nalimov's source, there are 292 TBs for the whole
set of 2-men (KK ...), 3, 4 and 5-men TBs. Without the 4+1 TBs there are 222.

Some TBs are symmetrical, like KNKN, and the newest code of Eugene looks like it
only needs only the nbw and not the nbb.
