That is two line notation.

But I can't get it right, here's my best permutation, I mean effort:

1 7 2 3 6 4 8 5 9

But...with that I get these cycles;

1 -> 7

2 -> 3

3 -> 6

4 -> 8 wrong

5 -> 9 wrong

6 -> 4

7 -> 2 wrong

8 -> 5

9 -> 1

I have 3 cycles wrong. I have tried many variations, for example;

(1 7 2) (3 6 4 8 5 9)

(1 7 3 6 4 2 8 5 9)

(1 7 2 3 6 ) (4 8 5 9)

But no, I just can't get it right.

And this shorter one is really close:

I want to achieve this:

1 2 3 4 5

2 1 4 3 5

Here is my best permutation:

(1 2) (3 4 ) ( 5 ) and that will be:

1 2 3 4

2 1 4 3

But 5 is missing after 4. How I get that 5 so that will be;

1 2 3 4 5

2 1 4 3 5

I would really appreciate help.
