Does the number 42 have any particular significance?
According to The Hitchhiker's Guide to the Galaxy, the number 42 is supposedly the reason for existence itself, but does the number 42 have any real-world importance?

The Ancient Egyptians believed that 42 demons were present at the judgment of the soul; 42 is also a perfect score in the International Mathematics Olympiad. But in modern maths its main significance is the fun it provides by popping up in strange places. My favourite example is the sequence 42424242 that occurs 242,422 places after the decimal point in the number pi.
