Okay, given a permutation, one, two, three, four, five, six, seven, eight.
00:07
Permutation is determined by two, three, five, one, four, six.
00:15
Okay, to find the orbit of this permutation, the first thing to do is to find the fixed point, okay? because the fixed point, those fixed points are also orbits, are already orbits.
00:30
So from observation, we know the sixth is the only fixed point in our permutation.
00:37
Then, now let's begin with the first one.
00:41
Okay, how do we do that? okay, from here we know one goes to two.
00:48
Okay, one goes to two, and it's our two, and two goes to three, two goes to three, and three goes to five, goes to five, where's our five? five is here.
01:06
And five goes to, let's just go back, and four goes to one.
01:14
So it is closed.
01:18
So we begin with one, we begin with one, and end up with one...
