The definition
merely requires that some ordering of the rows places the ones into consecutive
form, hence the matrix is deemed to have the consecutive ones property. The top
center matrix has the circular ones property because the rows can be rearranged
as shown on the bottom center so that all of the columns have circular ones. There
is no rearrangement of the rows which will place it into consecutive form so it does not
have the consecutive ones property. The matrix on the top right has neither a circular
form nor a consecutive form; there is no arrangement of the rows which achieves
either circular or consecutive ones.
