Many approaches for forgetting in Answer Set Programming (ASP) have been proposed in recent years, in the form of specific operators, or classes of operators, following different principles and obeying different properties. A recently published comprehensive overview of existing operators and properties provided a uniform picture of the landscape, including many novel (even surprising) results on relations between properties and operators. Yet, this overview largely missed an additional set properties for forgetting, proposed by Wong, and this paper aims to close this gap. It turns out that, while some of these properties are closely related to the properties previously studied, four of them are distinct providing novel results and insights, further strengthening established relations between existing operators. © Springer International Publishing AG 2016.
