  • Letter Envelopes

    I have recently received a number of letters. The inside of the
    envelopes have all included some measure to obscure the contents to
    prying eyes.

    Two included a geometric pattern, but the third, from Churchill, was
    more interesting, it contained the repeated sequence of digits as follows:

    078806697382548726870788066973825487268707880669738....

    Do we know what that sequence is? It is clearly not random.

    Apologies, if I have miss-transcribed the sequence.

    No 1s. Perhaps that's because 1 has fewer inked "pixels" to
    offer. But why they don't just print solid black is anyone's guess.

    Good guess and I figure that may very well be the answer given
    that there are a lot of "heavy" digits -- 6s and 8s.

    As for your question, it may just be a question of how much ink
    they want to use. In my experience all such obscuring patterns in
    "safety" envelopes are some kind of wavy lines, etc. and never
    just uniform black. I also wonder if people do not like using an
    envelope that is fully black inside.

    Ah, no. I should have said. Churchill is an UK insurance company. They
    had a British bulldog as a mascot.
