Method ringing is used to ring bells in churches, particularly in England. Suppose there are6bells that have6different pitches. We assign the number1to the bell highest in pitch,2tothe second highest, and so on. When the 6 bells are rung in some order—each of them exactly once-it is called a row. For example,1,2,3,4,5,6and6,3,2,4,1,5are two different rows.
