i could imagine two ways:
-place a R1 5-48 prim, rotate it by 7.5deg (360/48), then scale it
-inline the 1-6 prim and delete one segment
both have their disadvantages:
-the rotated+scaled prim will have a strange rotation matrix and strange connection points
-inlining loses all prim links and properties

-inline the 1-6 prim and delete one segment
