long words (say 10+ letters) with no repeated letters (35)

Chatgpt made a pretty good fist of it too, and my first example 'ambidextrously' was one of its first choices
what are some long words with no repeated letters
Uncopyrightable
Subdermatoglyphic
Ambidextrously
Unpredictably

For those who find such games lame, I'd use 'lamebrains' but unfortunately it has two 'a's

I also asked chatgpt:
find some long words with few different letters
To which it did well enough:
Bookkeeping
Beekeeper
Beekeeping
Bookkeeper
Peppermint
But weirdly: Bebop
Me: why did you include 'bebop' as an answer to 'find some long words with few different letters'
ChatGPT: I apologize for the confusion. You're right; "bebop" is not a long word, and its inclusion was an error. Thank you for pointing it out.

And then to: find some words longer than 15 letters with few different letters
Finding words longer than 15 letters with few different letters is quite challenging, as longer words often involve a greater variety of letters. However, here are a few examples:
Unrepresentativeness (19 letters)
Counterproductiveness (20 letters)

So I asked: find some words longer than 15 letters with few different letters and tell me how many different letters each word has and that threw it off:
Uncopyrightable (15 letters, 11 different letters)
Subdermatoglyphic (17 letters, 12 different letters)
Ambidextrously (14 letters, 12 different letters)
Dermatoglyphics (14 letters, 11 different letters)

Then: User antidisestablishmentarianism - how many letters and how many different letters
The word "antidisestablishmentarianism" has 23 letters, and it includes 11 different letters.
User: find a long word where the ratio of word length to number of different letters is maximum
It understood, and attempted, with meagre success.
User: Do you learn? Let me ask the same question again, and see if you make the same mistake. find a long word where the ratio of word length to number of different letters is maximum

Final response:
I don't learn in the sense of retaining information from one interaction to another, but I can use the information provided in the current conversation to improve responses and accuracy.

I was thinking unproductively but then there are two 'u's - till the penny dropped:
productively

syncopated - I was working on synchro but the n and c cause a problem with synchro+ words

any idea how many phobias are listed in wiki, or that there is a fear of knees or kneeling? genuphobia

recomendation........

wrong

fragmentious

The fragmentious destruction of the universe.

(It's a new word. Meaning to particleize something)

Not sure of the spelling of particleize. Thats a new word too.

So many people hide in the shadows of cs threads but finally work up the strength to come out of the ‘background’ to bloviate and express their negativity about word games.
