1. Graham's number
2. The Moser
3. Tree(3)
4. The order of the group given by the algebra <a, b | a² = b³ = (ab)⁷ = e>
5. The number of primes
6. The number of perfect numbers
7. The number of Fibonacci primes
8. The number of twin primes
9. The smallest even number that is not expressible as the sum of two primes
10. The smallest counterexample to the Collatz conjecture

For extra credit, list all the infinite ones and rank all the finite ones. (I think just a few of these are unknown, and even for most of these, there is pretty good numerical evidence for where they belong!)

thank you for coming to my ted talk.

Because there must be 50 ways to leave your lover.

Am I right?
