  1. How can the last digit be 2, in base 10? Wouldn’t that make it divisible by 2 and therefore not prime?

  2. Interesting note.

    Your formula for perfect numbers is off. Wikipedia says (changing notation to be able to type more easily)

    2^(pāˆ’1) * (2^p āˆ’ 1)

    Since 7 is a mersenne prime your formula would make 7*8 a perfect number when really it is 28 = 4 * 7 = 1 + 2 + 4 + 7 + 14
