is 2.16 (cf. Table 1) , thus they are close to each other .

The above points are important to the following discussion.  [*When a first-state has a FS which is superior than the other FSs (or the state has only one FS), the FS is expected to be dominant. In this case the state would have a clear geometric feature arising from the N*]{}$%
_{in}-$[*N*]{}$_{out}$[* structure of the FS, and appear to be crystal-like.*]{} However, when a first-state has a few nearly equally competitive FSs, its structure can not be uniquely predicted. Nevertheless, the Table 2 is a key to understand the electronic structures.
