EE:=COUNT(AA,5)=2 AND AA AND REF(BB,1) AND REF(BB,2) AND REF(BB,3);
GG:=COUNT(AA,6)=2 AND AA AND REF(BB,1) AND REF(BB,2) AND REF(BB,3) AND REF(BB,4) ;
MM:=COUNT(AA,7)=2 AND AA AND REF(BB,1) AND REF(BB,2) AND REF(BB,3) AND REF(BB,4) AND REF(BB,5) ;
NN:=COUNT(AA,8)=2 AND AA AND REF(BB,1) AND REF(BB,2) AND REF(BB,3) AND REF(BB,4) AND REF(BB,5) AND REF(BB,6);
OO:=COUNT(AA,9)=2 AND AA AND REF(BB,1) AND REF(BB,2) AND REF(BB,3) AND REF(BB,4) AND REF(BB,5) AND REF(BB,6) AND REF(BB,7);
PP:=COUNT(AA,10)=2 AND AA AND REF(BB,1) AND REF(BB,2) AND REF(BB,3) AND REF(BB,4) AND REF(BB,5) AND REF(BB,6) AND REF(BB,7) AND REF(BB,8);
