What’s an autogram An autogram is a self-referential sentence that writes out a count of its own characters - like the sentence above.
Updating just one letter’s count avoids getting stuck in any cycles of more than 1 and allows the process to run until it has found an autogram, if any exist. In practice, if this technique doesn’t find an autogram after a few million iterations I adjust the initial wording and try again. exclaimed the sentence as it enumerated its nine a’s, four c’s, four d’s, forty-four e’s, fourteen f’s, three g’s, ten h’s, nineteen i’s, five l’s, six m’s, twenty-three n’s, twelve o’s, four p’s, fifteen r’s, thirty-seven s’s, twenty-nine t’s, eight u’s, six v’s, seven w’s, six x’s, eight y’s, twenty-four comma’s, six hyphen’s, twenty-five apostrophe’s, and two !’s
