For the following, only letters unique to the spelling of the American English constructed name of the cardinal number shall be counted in determining the length of the cardinal number. Spaces, hyphens and commas are also excluded in determining length. For example, SEVEN has a length of 3 as the E occurs more than once in it spelling. Also note, in American English, the occurance of the connecting word 'and' is ommitted in the construction of a cardinal number's name.

1. What is the largest cardinal number of greatest length?

2. What is the smallest cardinal number of shortest length?

I am sure that someone will find something higher, but here is my last go. It has 16 unique letters in the word.
