The formula is:  f( (f(x+1 , 2) + 1) , 2)

where f(a,b) = a!/(b!(a-b)!)  and  a! = 1*2*3*....*(a-1)*a
and x= number of pieces wanted for the tablebase.

So since now x=5 (P,N,B,R,Q) we have:

f( (f(6,2)+1) , 2) = f(16 , 2) = 120

So you are right................

The correction is that Firefox don't display the multiplication dot
when i press ALT+0183. Instead it displays a ?
The html code for the dot is "&#183 ;" but i think CCC don't
convert this to a dot.
