There is a natural notion of well behaved algebraic weak factorisation system on a locally presentable category – which we will call an “accessible AWFS ”. There are important of examples of these which are not “cofibrantly generated” in any sense considered to date. I will describe such examples and explain what, in fact, they are generated by. This is joint work with Richard Garner.
