Also, 73 is the best number ever, because:
- It is the 21st prime number.
- The previous is 71, giving the 8th twin prime.
- It is also permutable with 37; 73 is a star number.
- It is the largest minimal primitive in the first 100000 primes.
- 73 is an emirp.
- The mirror of 73 (the 21st prime) is 37, the 12th prime.
- 21 = 7 * 3
- 21 in base two = 10101
- 73 in binary = 1001001, giving two palindromical numbers.
- 73 is the only prime repunit in base 8
- 73 is also the smallest factor of the first composite generalized Fermat's number in base 10 (10^4+1 = 10001 = 73 * 137.
Furthermore, 73 is the length of the Aribeco message, which in itself is AWESOME.
