## Abstract Let โชฏ~R~ be the preorder of embeddability between countable linear orders colored with elements of Rado's partial order (a standard example of a wqo which is not a bqo). We show that โชฏ~R~ has fairly high complexity with respect to Borel reducibility (e.g. if __P__ is a Borel preorder, t
