A Sri Lankan Mystery

A Sri Lankan Mystery

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

At first, it was thought that this was a test pattern, but today, estate executors discovered a storage room in Clarke's home filled with similar pages. 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.

One thought on “A Sri Lankan Mystery”

  1. Weird fascination with combinatorics? I have read that Newton’s notebooks contain pages where he has calculated logarithms out to dozens, if not hundreds of digits for no apparent reason. I’m thinking that Newton just had sort of a ramjet style brain that just had to be operating continuously at high intensity to be in its normal operating mode.

  2. Investigators estimate that the entire collection comprises about nine billion such words.

    The Nine Billion Names of God, perhaps?

  7. What lovely timing.

    Hey, don’t look at me.

    Things that I will do for the sake of an arguably-cute eulogy:
    Write a Perl script that generates permutations of a given set of characters.Estimate the volume taken up by 5.5 million sheets of paper.Adopt a vaguely reporter-like writing tone.

    Things I will not do:

    Engineer an incomprehensibly-devastating stellar event 3.7×109 years before I was born.
