According to Sheldon, what is the best number?
Answer 73
Sheldon claims 73 is the best number. As he would say, "73 is the 21st prime number. Its mirror, 37, is the 12th, and its mirror, 21, is the product of multiplying 7 and 3...and in binary 73 is a palindrome, 1001001, which backwards is 1001001."
