From an Eight Chain Thru, Facing Lines, or other applicable formations.

Square Thru until the original Centers become Ends of Back-To-Back Lines and until the original Outsides become Centers of Facing Lines; New Centers (working in the middle) do the anything call or complete the Square Thru n (continuing with alternating hands).

• The anything call or completing the Square Thru n is done by the Centers only, working in the middle of the set (Concentric).
• If no n or if anything is given, assume n is 4. Most callers nearly always supply n or anything so that there is no confusion.
• Several callers, myself included, call this as Mixed Up Square Thru, Centers go n More to clearly indicate the number of additional hands for the new Centers.
