You can't have two different sets with four equal numbers - it's not a very difficult thing, it's impossible to distinguish because they're identical! Given 4 numbers in the set, the 5th is uniquely determined. By example: 12, 3, 10, 18 *must* end with 7. The 5th number is not "random". Any randomness analysis should include only the first 4 numbers (or any other set of 4). In other words, there are only 4 degrees of freedom. In the fence analogy, you only have to choose where to place 4 poles; the 5th is fixed at the end. -- Gabriel Genellina -- http://mail.python.org/mailman/listinfo/python-list
