1\overset{\leftarrow}{I(1,2)} 12 123 1234 134 3134 313 13 143 123

\overset{I(1,1)}{\rightarrow} 1 \overset{I(2,2)}{\rightarrow} 12 \overset{I(3,3)}{\rightarrow} 123 \overset{I(4,4)}{\rightarrow} 1234 \overset{d(2)}{\rightarrow} 134 \overset{I(1,3)}{\rightarrow} 3134 \overset{D(4)}{\rightarrow} 313 \overset{D(1)}{\rightarrow} 13 \overset{I(2,4)}{\rightarrow} 143 \overset{C(2,2)}{\rightarrow} 123
