There are 36504 different possibilities.
The best way to think of this is how many options there are for each letter. There are 7 possibilities for the first letter. Then there are 6 possibilities (out of the remaining letters) for the second latter. Then 5 possibilities for the next, and so on. The total number of possibilities will be 7x6x5x4x3x2x1, which equals 5,040. So there are 5,040 different ways to arrange 7 letter words.
6P4 = 6!/(6-4)! = 6 * 5 * 4 * 3 = 360 four letter permutations from 6 different letters.6C4 = 6!/[4!∙(6-4)!] = 15 four letter combinationsfrom 6 different letters.
If they are all different, then 40320.
40,320
64 different arrangements are possible.
Hhhh
First you decide how many different symbols may be used. For example, with only lowercase letters, there are 26 symbols. If you permit lowercase and uppercase, there are 52 symbols. If you include digits too, that increases to 62. If you include a few special symbols (such as period, coma, hyphen, etc.), you will get a few more. Then you raise that to the power 6, since in each position you can have (for example) 26 different possibilities, and the possibilities are independent. That is, with only lowercase letters, you have 26 options for the first position, 26 options for the second, etc., resulting in 26 x 26 x 26 x 26 x 26 x 26 = 266. This assumes there are no additional restrictions as to what letters you can use - for example, there may be repeated letters. If on the other hand 6 specific letters are given, and you must rearrange them, the number of possibilities is only 6 x 5 x 4 x 3 x 2 x 1. This is written as 6! (the factorial of 6).
there are 36 different combination possibilities. Try them all.
If all letters and numbers are allowed, the possibilities are 26x26x10x10x10x10. So: 6760000 different plates.
There are different kinds of business letters that are written for different purposes. Common business letters include sales letters, order letters, adjustment letters, complaint letters and so many others.
Letters are written for different purposes. Some of the types of letters include recommendation letters, resignation letters, thank you letters, acceptance letters and intent letters.
One way to work this out is to imagine that you have a bag containing all 26 letters of the alphabet.Take one letter from the bag. It could be any one of the 26, so there are 26 possibilities for your first letter.Take another letter from the bag. This time there are only 25 letters in the bag (you've already taken one out, remember!). So you have 25 possibilities for the second letter.So far there are 26 x 25 (= 650) possibilities for your first two letters. (AB, BA, AC, CA, AD, DA, etc)Now take your third letter from the bag. But remember, there are now only 24 letters remaining.So, for 'from 26 chose 3', altogether you have 26 x 25 x 24 possibilities, which comes to 15,600 different combinations of three different letters.
When you unscramble the letters mmanrya you get rammy, mayan and amman. There is not a single word that uses all seven letters that were given. Additional words that can be made from those letters include ray, yarn, Mary, and ran.

Dragnets.
Different types of letters have different parts. Personal letters include: heading, salutation, body, closing, and signature. Business letters include: heading, date, inside address, greeting, subject line, Body, closing, signature and writer's identification, and copies or enclosures.
Two letters = 26*26 = 676 possibilities 4 digits = 104 possibilities (if numbers such as 0000 are permitted). All in all, 6.76*106 possibilities. That should keep Oxnard University going for a few years.
