generating random numbers with hamming distance 4

Hi I want to genrate 10 random 32 bit binary numbers with hamming distance 4 and 8.

11010110010101010101010101010101
11010110010101010100010101010010

if we look carefully at these two binary numbers they differ at 4 places hence hamming distance 4. Now I want to genrate these numbers randomely such that 1 and 2nd, 2nd and 3rd, 3rd and 4th 4th and 5th etc. are pairs of numbers at haaming distance 4.a and I want to generate 10 such numbers

At this point, I suspect that you may not be aware of the rule stating:
(6) Do not post classroom or homework problems.


With some trepidation, here are numbers meeting your stated requirements...
Code:

But since this seems like homework, I won't post the script that generated the numbers
# 3  
I just wanted know how can you say that this is my class homework??? Smilie I need this script just to make my work easier so that I don't have to do this manually. Anyway I don't think I will be needing script since I have already done this by just changing bits manually and then calculating integer value.
