That is exactly the effect that Shriram was looking for. Think about the decimal numbers in the range 1-200. How many start with 1?- More than half. The range 1-1000 is an exception. But natural distributions are not uniform over a fixed range. They are bell curves of one sort or another. If you have a natural random distribution there will always be a skew toward the smaller digits. It is quantified as Benford's law. -- Chris Stephenson c...@cs.bilgi.edu.tr _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
