Nice stitch for stretchy chunky ribbing that looks interesting and compound. It is knitted like something in-between seed stitch and classic ribbing. Another name is English Mock Rib.

The obtained fabric looks exactly the same from both sides, so it works great for reversible garments like scarves or afghans.
