Quadruple formation is analogous to Triple formation except that there are 4 occurrences of the given formations instead of 3. EN: 20

When doing a call in Quadruple formation, work only with the dancers and phantoms within your formation. Shape-changing calls are allowed and will end in a different set of Quadruple formations. EN: 30

Quadruple formation is clearer for dancers than Split Phantom formation, as dancers only need to track their 4 spots, rather than the 8 spots for Split Phantom. EN: 40

Typically, a long axis traverses through the entire set of 4 formations. Visualize surrounding each formation within an imaginary bubble. The long axis is the line that traverses the 4 formations, connecting the four bubbles in a linear fashion. Dancers work within their bubble to do the given call, which may be a shape changer. Upon completion of the call, the new formation (including any phantoms) is still enclosed in a bubble shaped to enclose the new formation, and the bubbles must still be connected in a linear fashion. Stay within your formation and adjust the four bubbles as necessary to line up side-by-side along the original long axis. EN: 50

Assume that phantoms are facing in whatever direction is needed to do the given call. For Quadruple Wave, phantoms must be facing such that each formation is a Wave. The caller can optionally be more specific and give the exact name of the formation (e.g., Quadruple R-H Two-Faced Line). EN: 60
