This program is(was) available at bob's FTP site. It proceduces the folowing output with namegen 5 5. If you notice same tables you think are missing then let me know. The total amount in this list is 110. According to this program I get the folowing table: #pieces | #tables 2 1 3 5 4 30 5 110 6 365 7 1001 8 2520 9 5720 10 12190 list of all 5 men tables: KPPKP KPPKN KPPKB KPPKR KPPKQ KNPKP KNPKN KNPKB KNPKR KNPKQ KNNKP KNNKN KNNKB KNNKR KNNKQ KBPKP KBPKN KBPKB KBPKR KBPKQ KBNKP KBNKN KBNKB KBNKR KBNKQ KBBKP KBBKN KBBKB KBBKR KBBKQ KRPKP KRPKN KRPKB KRPKR KRPKQ KRNKP KRNKN KRNKB KRNKR KRNKQ KRBKP KRBKN KRBKB KRBKR KRBKQ KRRKP KRRKN KRRKB KRRKR KRRKQ KQPKP KQPKN KQPKB KQPKR KQPKQ KQNKP KQNKN KQNKB KQNKR KQNKQ KQBKP KQBKN KQBKB KQBKR KQBKQ KQRKP KQRKN KQRKB KQRKR KQRKQ KQQKP KQQKN KQQKB KQQKR KQQKQ KPPPK KNPPK KNNPK KNNNK KBPPK KBNPK KBNNK KBBPK KBBNK KBBBK KRPPK KRNPK KRNNK KRBPK KRBNK KRBBK KRRPK KRRNK KRRBK KRRRK KQPPK KQNPK KQNNK KQBPK KQBNK KQBBK KQRPK KQRNK KQRBK KQRRK KQQPK KQQNK KQQBK KQQRK KQQQK
