A single Berge k-move is denoted as { j i }, in which case, the pieces in the positions i,i+1,...,i+k-1 are moved to the vacant holes j,j+1,...,j+k-1. Successive moves are concatenated as { j i } U { l k }, which means perform { j i } followed by { l k }. Often a move fills an empty hole created as an effect of the previous move, the resulting notation { j k } U { k i } is abbreviated as { j k i }, and is extended to more than two such moves as well.
