Assuming The height of Individuals = 1, 2, 3, 4,5, 6 in ascending order i.e. 1 being shortest and 6 being tallest

From the Given instructions, we can infer that 1 must be on the lower left and 6 must be the upper right. So 2 position are fixed.

Case 1: The usual arrangement.
4_5_6 <--- row 2
1_2_3 <--- row 1

Case 2: Bring 5 down and take 3 up
3_4_6
1_2_5

Case 3: Bring 5 down and take 2 up
2_4_6
1_3_5

Case 4: Bring 4 down and take 3 up
3_5_6
1_2_4

Case 5: Bring 4 down and take 2 up
2_5_6
1_3_4


5 cases total.
