Podle mojí hypotézy mají obecně polynomy tvar: nk - 3k(k-1)/2*nk-1 + (9k4/8-29k3/12-k2/8+23k/12-1/4+(-1)k/4)*nk-2 - ...
(sekvence u třetího členu by tedy měla pokračovat takto: 0, 2, 30, 139, 407, 943, 1879, 3378, 5626, 8840, ...)
Jelikož vzorce pro rozmístění k dam na šachovnici kxn platí vždy až od jistého n, jsou v následující tabulce uvedeny počty i pro malá n, kde vzorce ještě neplatí (červená čísla). Sloupec vpravo představuje počty rozmístění vzájemně se neohrožujících n dam na šachovnici nxn (jehož speciálním případem je známý problém 8 dam, který vyřešil již v roce 1850 slavný matematik Gauss). Odvodit obecný vzorec se zatím nepodařilo a i jen tyto dílčí výsledky naznačují, o jak obtížný problém se jedná (porovnejte s diagonálou v tabulce).
