Well, if memory serves: 12 = 2 * 6 bits for the positions of the Kings 62 bits for a mask of the other occupied squares 100 bits for a 30-digit (decimal) integer specifying their contents This is exclusive of the other six bits that you always need for the side on move, castling rights, and en passant. Representations smaller than 192 bits (24 bytes) are not likely to have much more than curiosity value unless one can get down to 160 bits (20 bytes).
