What's the difference between symmetry and tetradic?
Symmetry
Definition:
(n.) A due proportion of the several parts of a body to each other; adaptation of the form or dimensions of the several parts of a thing to each other; the union and conformity of the members of a work to the whole.
(n.) The law of likeness; similarity of structure; regularity in form and arrangement; orderly and similar distribution of parts, such that an animal may be divided into parts which are structurally symmetrical.
(n.) Equality in the number of parts of the successive circles in a flower.
(n.) Likeness in the form and size of floral organs of the same kind; regularity.

Tetradic
Definition:
(a.) Of or pertaining to a tetrad; possessing or having the characteristics of a tetrad; as, a carbon is a tetradic element.
Example Sentences:
