You're missing two
e and pi are both extremely important. Basically we need 0, 1, i=sqrt(-1), e and pi. infinity isn't a number, it's a limit and can be taken in numerous different ways and not all infinities are the same size. Take the number of integers, 1, 2, 3, 4....infinity. Now take the number of half integers, 1/2, 1, 3/2, 2, 5/2, 3...infinity. The infinity of half integers is clearly twice the size of the infinity of integers. Fortunately these are both countable infinities.
