Btw, the question is worded badly, you should scald your teacher.
so what u mean with n-1 factorial.. how ca i draw them
Place your first person in a seat. Then for the first 3 pictures put a different person in the seat clockwise of him. For each of those 3, put the remaining 2 people in different seats. Boom, 6.
aaaaaaaa,,, yea look he said this are cosider the same |dw:1323555360660:dw|
Then your teach is wrong, they aren't the same.
They are only the same if you can rotate the table so they look exactly the same.
i think thats what he means
Yup, so the two pictures you drew are different as you can't rotate one to make the other.
i got |dw:1323555627767:dw|
My apologies, I could only see the first drawing in each of your pictures as my window is small. In your second picture they are the same yes,
Okay now for each of those pictures, just swap over the 2 on the bottom and you have your 6.
mm i cant look
Why did you move your A? With your 3 you got, just swap the bottom row and keep the top row the same.
will happen the same
ABCD, ABDC, ACDB, ACBD, ADBC, ADCB are your 6 tables. No it won't happen the same.
What is your picture trying to show? You have 6 different tables there like I told you.
the first three are different arrangements but the three next it looks the same if u turn the table
well no too much
You're wrong, look more carefully. You have 6 distinct tables.
yeaa... i can see now
so are we still using (n-1)!
