Q: What trigraphs (three-letter combinations) occur in only one word?

A: Here is a list of all the trigraphs which occur exactly once in the union of
''Official Scrabble Words'' (First Edition), the _Official Scrabble Players
Dictionary'' and ''Webster's Unabridged Dictionary (Second Edition)_,
together with the words in which they occur.

The definition of "word" is a problematic.  For example, lots of words
starting deoxy- contain the trigraph `eox', but no others do.  Should
`eox' be on the list?

Common words are marked with a *.
