An atom must have six parts if six atoms simultaneously conjoin with it from six directions.

Further, if there were a simultaneous conjunction of an atom with other six atoms coming from the six directions, the atom would have six parts because that which is the locus of one atom cannot be the locus of another atom. If the locus of one atom were the locus of the six atoms, which were in conjunction with it, then since all the seven atoms would have the same common locus, the whole mass constituted by the seven atoms would be of the size of a single atom, because of the mutual exclusion
