A Sri Lankan Mystery
The last thing that came out of recently deceased author Arthur C. Clarke’s printer was a sheet that said:

The oldest ones were written out by hand in notebooks. Later ones appear on reams of fanfold printer paper, while the most recent ones appear to have been printed on a laser printer and bound together.
No two words are the same. All use only the letters A C E H K L R S T U. It is not known why these letters were significant, nor which rules were used to generate the "words". For instance, although many "words" contain two, three, or four instances of the same letter, never does a letter appear three times in a row.
With ten columns of eighty "words", each double-sided sheet holds 1600 "words". Investigators estimate that the entire collection comprises about nine billion such words.
