This form allows you to generate randomized sequences of integers. The randomness comes from atmospheric noise, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs.
Note: A randomized sequence does not contain duplicates (the numbers are like raffle tickets drawn from a hat). There is also the Integer Generator which generates the numbers independently of each other (like rolls of a die) and where each number can occur more than once.
