The Action

This is sort of the last half of Chain Reaction.

Typically from a Trade by: ends Hinge and then Trade, while the centers make a right-hand star by doing a 1/2 Reverse Swap Around, and turn the star 1/4. Then finish like a Chain Reaction — center line Cast off 3/4 while the others "move up".

The ends' part is exactly the same as Linear Action.

The centers' part starts like Star to a Wave or Tag the Star, except that the star turns only 1/4, and it isn't important who the points and centers are.
