Confusion danger: This class is sometimes called evenholefree .
;
The map shows the inclusions between the current class and a fixed set of landmark classes. Minimal/maximal is with respect to the contents of ISGCI. Only references for direct inclusions are given. Where no reference is given, check equivalent classes or use the Java application. To check relations other than inclusion (e.g. disjointness) use the Java application, as well.
Problems in italics have no summary page and are only listed when ISGCI contains a result for the current class.
