For example, from a Butterfly formation, there are two Diagonal Columns or two Diagonal Lines | Waves.

Normally, calls done within a Diagonal Column|Line|Wave start and end on the four footprints of the Diagonal Column|Line|Wave. Occasionally, from a Butterfly, the caller may give a call which rotates the Diagonal by 90° (such as Diagonal Wave Lockit or Diagonal Wave Spin The Top). In this case, the dancers end in the footprints of the other 1x4.
