This sentence has three As, two Cs, two Ds, nineteen Es, six Fs, two Gs, five Hs, ten Is, two Ls, twelve Ns, nine Os, five Rs, twenty six Ss, sixteen Ts, four Us, four Vs, eight Ws, four Xs, and two Ys.
How many other similar self-referential statements can you come up with (there exist a relatively small finite number of possibilities)?

I like that answer... but I *think* that DJ means the sentence specifically says exactly how many of each letter it has (rather than saying 'has fewer than').... In which case, one must take into account the spellings of each number of each letter. (e.g., changing the sixteen in front of the 'Ts' to a seventeen, would maintain the number of s's and t's but change the number of e's, x's v's and i's... etc...)
Of course, perhaps, as Penny said, "I am totally misreading this puzzle (wouldn't be the first time)".
