    This is an immensely impressive construction. Thank you!

    According to https://www.visca.com/regexdict/, “futility” and “infinity” are two longest pentomino words in the English language. Search for ^[filnptuvwxyz]{7,}$ to get all with seven letters or more; some fun runner-ups are “fulfill”, “utility”, and “willful”.

    I’ve known this for a few years now, but it never occurred to me to place one or both words on a grid whose area is _not_ a multiple of five and then use the holes to force uniqueness. This is a very clever way to go about it; still, even so it must have been very difficult to get the puzzle to work.

    The race for longest coherent pentomino-words-only sentence in a puzzle is on!
