%F Suppose T is a rectangular array consisting of positive integers, each exactly once. The transposition sequence of T is here defined by placing T(i, j) in position T(j, i) for all i and j.

%e Start with the northwest corner of T:

%e a(1)=1 because 1=T(1,1) and T(1,1)=1.

%e a(2)=4 because 2=T(1,2) and T(2,1)=4.

%e a(3)=6 because 3=T(1,3) and T(3,1)=6.

%e a(13)=17 because 13=T(3,2) and T(2,3)=17.
