Isomers

Isomer

1. (Science: chemistry) One of two or more molecules that have the same chemical formula but have a different stereochemical arrangement of their atoms.

2. (Science: radiobiology) nuclides having the same number of neutrons and protons but capable of existing, for a measurable time, in different quantum states with different energies and radioactive properties. Commonly, the isomer of higher energy decays to one of lower energy by the process of isomeric transition.

Re:

... to represent the conscious ideals not yet common in our morphology. Chains with more than three Carbon atoms can form many different structural isomers to make rings, cubes, triangles or branch off. These "isomers" have similar (but not exact for example branched design more easily ...
