It has two distinct forms, which are mirror images ( or " enantiomorphs " ) of each other.
12.
Taking the odd permutations of the above coordinates with an even number of plus signs gives another form, the enantiomorph of the other one.
13.
In doing so, the vertices of the two enantiomorphs coincide, with the result that the full compound has two triangular prisms incident on each of its vertices.
14.
In doing so, the vertices of the two enantiomorphs coincide, with the result that the full compound has two pentagrammic prisms incident on each of its vertices.
15.
In doing so, the vertices of the two enantiomorphs coincide, with the result that the full compound has two pentagonal prisms incident on each of its vertices.
16.
That is, the more an object has been rotated from the original, the longer it takes an individual to determine if the two images are of the same object or enantiomorphs.
17.
When something comes in multiple forms which are each other's three-dimensional mirror image, these forms may be called enantiomorphs . ( This nomenclature is also used for the forms of certain chemical compounds ).
18.
The enantiomorphs are designated right or left handed, according to whether they rotate the plane of polarised light to the right or to the left . Sometimes it is clear from the outward form of the crystal whether it is right or left handed, and sometimes optical methods are needed to determine this.
