So i have 6 different symbols! I need to make as many combinations of 4 of the 6 symbols as possible without using the same symbol more than once in a combination. How many possible combinations are there than meet that criteria and i would appreciate a formula if thats ok too. Thanks.
exclamation sorry. i havent used this forum before so im not used to the math lingo :/
Yes yes, but for example lets say i have letters A B C D E F
I want to make as many combinations of four as possible out of them;
A B E D
A B D F
but i cant have any repeat combinations and there cannot be any A A C E stuff going on either. No letter used twice.
Ok apperantly there is a missing piece to the puzzle. When trying to find all the possible combinations i came across multiple duplicates in combination. The spots are a great help yet they determine the total number of possible "orders" not combinations. For example when using the spots shown above i get this
6 5 4 3
_ _ _ _ This gives me 6 choices for spot 1 and 5 for spot 2 and so on so that the same letter isnt used over again in the sequence, BUT this is what happens:
A B C D A C B D
_ _ _ _ _ _ _ _ See. Although the sequence is different they are still the same combination :/ I need a way to determine only the possible combinations. Thank you.
