Any 4 from 26 in any order is (26 x 25 x 24 x 23) = 358800. if You can't use ACBD and ABCD then the answer is 14950
6 taken 4 if all are distinct. if some are same, it will become 6 taken 4 over the product of the factorial of the frequency of every character.
P (26,4) = 26x 25x24x23 = 358800
The number is 26*25*24 = 15600.
If the numbers and letters can be repeated then there are 45,697,600 possible outcomes. If the letters and numbers can not be repeated there are 32,292,000 possible outcomes.

The possible arrangements of the letters N, O and T are :don'twontnotsnotrotknotnothing.......... and more....... just take a clue jeez........
Any 2 from 26 = 26 x 25 = 650 if ab and ba are regarded as separate, otherwise 325.
Five
There are 5 letters: a c e f and h.If the letters can be repeated, then there are five possibilities for each space in the four-letter arrangement. The number of arrangements then is:5*5*5*5 = 54 = 625.

In the word "function" you have 8 letters. 6 different letters and 2 equal letters.The number of different arrangements that are possible to get are:6!∙8C2 = 720∙(28) = 20 160 different arrangements.
There is no formula: it is a process of swapping letters in a systematic manner.
