This does not mean words. It just wants to know how many combinations of the single letters you can have. ie: a,b,c,etc., ab, ac, ad, etc., abc, abd, abe, etc., abcd, abcf, etc.

Hi John B. In spite of the wording of the question, I suspect the student has misinterpreted the question. What is probably required is the permutations of the 26 letters of the alphabet, which I am sure you are aware is 26P26. I seriously doubt that the question requires the sum of all the possible lengths from 1 to 26.

First Assumption - no repitition is allowed.
Second Assumption - any length, from 1 to 26 letters

Notation P(n,q) is the number of permutations of q elements from a set of size n.

P(26,1) = 26
P(26,2) = 26*25
P(26,3) = 26*25*24

The total (using the above assumptions) becomes the sumnation of all P(26,q) as q goes from 1 to 26.

That is P(26,1) + P(26,2) + P(26,3) + .... + P(26,25) + P(26,26)

Otherwise, as other have noted, it is an infinite amount because you can just keep adding letters at the end to cause a new combination

You do not clarify your question.
Those 26 letters are used once in a word or combination or as many times you want?
If it is once, then the second answer to your question should do it for you.

In order to answer the question you need to know combinations of how many. The general formula is

C(26,n) = 26!/((n!)(26-n)!)

where n is the number of lettersin each combination.

It depends how do you want to combine them...2 by 2, 3 by 3, 26 by 26.
If you combine 26 letter by 26 you have only one version.
If you want to arrange them (a, b, c....to a, c, b.....)
the formula is 26!/(26-26)!= 26!/0!= 26!/1= 26!=

It depends on the length of the word. Since, technically, you can have a 'word' that is infinitely long, the possibilities are infinite as well.

If you limit yourself to a certain letter length, however, then it is a different story.

Since there is no real limit to the length of the words that can be formed, and letters are repeated in words, a nearly infinite number. ~

in each cobination a letter is there or not there so 2 choices for each letter, so number of combinations = 2^26
