Statement 3 (The Mirror Effect of the CTC)
The mirror effect in the CTC exists between pairs of all rows such that
(i)
l ( 47 − i , j ) + l ( i , j ) = { q j + 1 , if i ≠ j and i + j ≠ 47 2 q j + 1 , if i = j or i + j = 47 ,
for i = 1 , 2 , ⋯ , 23 , j = 1 , ⋯ , 48
(ii)
l ( 47 , j ) + l ( 48 , j ) = { q j , if j = 1 , ⋯ , 46 2 q j , if j = 47 , 48 Math_121#
