[edit] Significance of the number
Nick Montfort, in his book Twisty Little Passages (ISBN 0-262-13436-5), suggests that the number was chosen because in its written form it falls naturally into two parts with an unusual relationship:
- 69 in hexadecimal is 105 in decimal
- 69 in decimal is 105 in octal
and also because 69 is the common name of a sexual position.
The same natural relationship applies to 1,001, 2,002, 3,003, 4,004, 5,005, 6,006, 7,007, 64,100, 65,101, 66,102, 67,103, and 68,104. However, 69,105 is the highest number with this property.
