There is exactly one word in the Official Scrabble Players' Dictionary
with the consonant/vowel pattern "cvvvvvc". (It's *miaoued*.)
There are many other c/v patterns for which this is also true. There
are many patterns for which there are exactly 2 words. There are many
patterns for which there are exactly 3 words, and so on. ... The
first number for which there is *no* pattern with exactly that
many words is 37.
