No, it's ok. Per position of the two Kings, the index is an n-cube where 'n' is the number of types of pieces after the King ... and where the length of each dimension can be worked out based on the type of piece and the number of them (and the positions of the two Kings). You also need to know the order in which pieces are 'placed' on the board after the Kings to make up the position you are looking at. The formulae are in the paper - and eminently computable: no combinatorics required.
