12 Matrices come in two varieties: 3x4 and 2x6. 3x4 setups look like Triple Lines or Columns. 2x6 setups look like Triple Boxes. Either may be configured as columns or lines.
In all 12 Matrix setups, those facing out of the grand setup act as leaders, all others do the trailers. part of the call. Reevaluate your position as leader / trailer after each part of the call.
