How many permutations of 4 are there?

256 permutationsIn the first position we have 4 number options, so like before place a “4” in the first blank. Since we are allowed to reuse numbers, we now have 4 number options available for the second digit, third digit, and fourth digit as well. By allowing numbers to be repeated, we end up with 256 permutations!

What does ∩ mean?
