[Split] [Interlocked] Phantom Columns, Lines, Waves, Boxes, Diamonds, 1/4 Tags, etc.
These are the generalizations of things like Split Phantom Waves, introduced at C3A.
At C4 all combinations are legal.
Four 4-person setups (considering a 1/4 tag to be a "single"
4-person setup) are arrayed one after another. With the "Split
Phantom" concept, the two adjacent groups on one side work together,
as an 8-person formation, as do the two adjacent groups on the other
side. With the "Interlocked Phantom" concept, each end group works
with the far center group. With the "Phantom" concept, the center
groups work together and the outer groups work together.
When 1x4 setups are involved, they may be end-to-end, forming virtual
1x8 setups. The complete actual setup is a 1x16 in this case. Similarly
diamonds or 1/4 tags may be point-to-point.
Shape-changers are allowed. The split or interlocked nature of the
setups persists.
