"Symmetrically distributed letters" means that the letters are equidistant from the center of the alphabet, or the same distance from their respective ends (similar to what you would see in a reverse alphabet cypher code).

The longest word with horizontal symmetry (if you held a mirror to the word, along a horizontal line across the middle, you would see the whole word between the reflection and the word half it was reflecting) is COCCIDIOCIDE.
Other words with horizontal symmetry:
*BEDECKED
*CHECKBOOK
*CHOICE
*CODEBOOK
*COOKBOOK
*DECIDED
*DIOXIDE
*EXCEEDED
*HIDE
*ICEBOX
*OBOE

Words with vertical symmetry:
*MOM
*WOW
*TOOT
*TAT
*TIT
*TOT

Upper case "BID" is horizontally reflective while lower case "bid" is vertically reflective.

"SWIMS" has 180-degree rotational symmetry.
