Random Integer Set Generator

This form allows you to generate random sets 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.

This is a premium service

You can try it out with the default values, but if you want to modify any of the fields, you should login or register for an account.

Step 1: The Sets

Generate set(s) with unique random integer(s) in each.

Each integer should have a value between and (both inclusive; limits ±1,000,000,000).

The total number of integers must be no greater than 10,000.

Step 2: Display Options

Each set will be printed on a separate line. You can choose from the following extra options:
Number the sets sequentially
Use commas to separate the set members
Sort the members of each set in ascending order

You can select the order in which the sets are printed:
Print the sets in the order they were generated
Order the sets by the values that occur in them (in this case, you should also consider sorting the members of each set)
Print the sets in random order

Step 3: Go!

Be patient! It may take a little while to generate your sets...
