Having got curious about the mathematical properties of the number 23, I started exploring and here’s what I found interesting from what I have seen on the web:

- 23 is the smallest prime number with consecutive digits.
- 23! is 23 digits long.
- 23 = 1
^{4}+ 2^{3}+ 3^{2}+ 4^{1}+ 5^{0} - 10
^{23}– 23 = 99,999,999,999,999,999,999,977 is the largest 23 digit prime. - According to the birthday paradox, in a group of 23 (or more) randomly chosen people, the probability is more than 50% that some pair of them will have the same birthday (are we not coming to the topic now ?!!)

**Oh by the way, Happy XXIII ^{rd} to me** 🙂
