8x32 bar, 3 couple reel in a set of 5 couples.

2nd, 3rd and 4th couple start and dance the reel normally as follows:

1-8 C2 set, cast off for two, lead up the middle to first corners.

9-12 C2 set to and turn first corners,

13-16 C2 balance in line with corners all holding hands ladies facing men's side. C2 leaving corners, turn BH 1 1/4 facing 2nd corners.

17-22 set to and turn 2nd corners, balance in line.

23-24 C2 cross to own side 3rd place.

25-32 C324, six hands round and back.

Second time around, 1st and 3rd couples start the dance. Couple 2 and 4 move up after 1 and 3 have casted. Fourth couple which is in now in third position help as corners both up and down. In other words L4 is first corner with first couple, while M4 is first corner with 3rd couple. After balancing in line (that is two lines) turn and face second corner, L4 is second corner with 3rd couple and M4 is second corner with first couple. Finish with all forming a circle. So:
 
1-8    C1 and C3 set, cast off for two, lead up the middle for first
corners

9-12 C1 and C3 set to and turn first corners,

13-16 C1 and C3 balance in line with corners all holding hands ladies facing men's side. C1 and C3 leaving corners, turn BH 1 1/4 facing 2nd corners.

17-22 set to and turn 2nd corners, balance in line.

23-24 C1 cross to own side 2nd place, C3 cross to own side 4th place.

25-32 C21435, ten hands round and back, C3 slip to bottom.

After that repeat with 2nd, 3rd and 4th couple only, etc. until the last time when the finish is again all hands around.

 
Dance is 8x32
1)    From original sequence   1, 2, 3, 4, 5
2)    becomes 1,3,2,4,5
3)    then 3, 1, 4, 5, 2
4)    then 3, 4, 1, 5, 2 
5)    then 4, 3, 5, 2, 1
6)    then 4, 5, 3, 2, 1
7)    then 5, 4, 2, 1, 3 
8)    then 5, 2, 4, 1, 3
 
So couples 1, 3 and 4 dance three times while couple 2 does it twice and couple 5 only once.
