Just came across a interesting article on Wikipedia on super primes.
Wait a minute, you mean besides primes we also have super primes, like besides Superman, we have super-Superman, I can pick up voices like this. Well, super primes are primes that occupy prime-numbered positions in the list of primes. Get it? If you don't, don't fret. Here is a table to show you what I mean:
| List of prime numbers | Position in list of primes |
| 2 | 1 |
| 3 | 2 |
| 5 | 3 |
| 7 | 4 |
| 11 | 5 |
| 13 | 6 |
| 17 | 7
|
| 19 | 8 |
| ... | ... |
| (Highlighted in violet are the primes that correspond to the numbers highlighted in the right column) | (Highlighted in blue are the prime numbers) |
From the table, we can see that the prime 3 is the 2
nd prime number, the prime 5 is the 3
rd prime number, the prime 11 is the 5
th prime number and the prime 17 is the 7
th prime number. Hence, the super primes are the primes 3, 5, 11 and 17.
What do you think about Superman, er, I mean, super primes?
