I want to compute the possible combinations of a password consists of 8 digits of: alphabetical letters (26), numbers (0-9), symbols and punctuations.

In order to compute this, I have to know the total no. of possible characters and raise this to the power of length of the password. However, I do not know how many possible symbols or punctuations are there? Can any one help with a reference if possible please.
