There is a lot of literature on the subject of short English pangrams, that is, sentences that contain every letter.
But I am curious what the shortest, or at least some of the shortest, sentences are that are not so strictly defined. I would like a sentence that contains at least 25 unique letters, but not necessarily all 26.
For example, the sentence "Quick jigs vex Nymph of Bad Waltz" contains 25 unique letters and has a total length of 27 (that is, 2 characters [in this case 'a' and 'i'] are repeated). Are there valid English sentences that fit this criteria with 26 or even only 25 letters?
