calculate the number of possible number of words If one word can be at most 63 characters long. It can be combination of :


*

*letters from a to z

*numbers from 0 to 9

*hyphen - but only if not in the first or the last character of the word


I'm trying to calculate possible number of combinations for a given domain name. I took stats facts here :

I have a very poor, elementary level of math so I've got this address from a friend to ask this. If someone could write me a formula how to calculate this or give me exact number or any useful information that would be great.

Close - but 26 letters plus 10 numbers plus the hyphen is 37 characters total, so it would be
(36^2)(37^61)
Now granted, that's just the number of alphanumeric combinations; whether those combinations are actually words would require quite a bit of proofreading.
