Bit of Numerology

by Adam C. Engst

Bit of Numerology -- We hit these triple identical digit issues of TidBITS every couple of years, but this is one of the most notable, since 666 is the so-called "number of the beast" from the Bible's Book of Revelation (Chapter 13, verse 18). But the number has additional meaning in the Macintosh world, where $666.66 was the initial price of the Apple I and where the now-relevant Unix command chmod 666 unlocks certain problematic files. It turns out the number has many other mathematical properties, as you can read at Mike Keith's page on the topic. I particularly like the last one. [ACE]
