Left Eight By [NOL]: Outsides Mirror 
  Grand Chain Eight and Roll as Centers do the anything call.  
  Note: the word Left applies only to the outsides. 
Note: Some callers use Eight By anything as if it was
  the same as Own The Outsides Grand Chain Eight & Roll By anything.
  For example, from an Eight Chain Thru: Eight By 1/2 Square Thru.  
  We believe that this usage of Eight By is invalid.
