Serpentine Rl Right Entry Bundle

Gallery / Serpentine Layout

A two-line boustrophedon fold with both rows packed into one grid cell, so the top row's RIGHT exit descends straight into the direction: RL return row's RIGHT entry. Leaving and arriving rightward is a half-turn, so the bundle re-nests across the fold: the line on the top track going out rides the outer lane round the corner and lands on the bottom track coming back (issue #1767).
