- "Knot" entities include prime knots up to 10 crossings, as well as some special infinite families.
- "Knot" entity classes include common mathematical types of knots, such as "Alternating", "Chiral" and "Torus", together with the negations of these.
- Mathematical properties are available for most "Knot" entities that are concisely representable and either well known or straightforward to compute. Properties for a small number of special parametrized family members are computed on the fly.
- Some properties are available for the "Knot" entity type as a whole and can be given using the form EntityValue["Knot",property]. Such properties include:
"Properties" the list of available properties "PropertyCanonicalNames" the standard names of available properties "SampleEntities" a sample list of available entities (typically of length 10) "SampleEntityClasses" a sample list of available entity classes (typically of length 10) "EntityCount" number of entities available "Entities" the list of available entities "EntityCanonicalNames" the standard names of available entities "EntityClasses" the list of available entity classes "EntityClassCanonicalNames" the standard names of available entity classes "PropertyClasses" the list of available property classes "PropertyClassCanonicalNames" the standard names of available property classes "PropertyCount" number of properties available
- The following annotations can be used in the third argument of EntityValue["Knot",property,annotation]:
"EntityAssociation" an association of entities and entity-property values "PropertyAssociation" an association of properties and entity-property values "EntityPropertyAssociation" an association in which the specified entities are keys, and values are a nested association of properties and entity-property values "PropertyEntityAssociation" an association in which the specified properties are keys, and values are a nested association of entities and entity-property values "Dataset" a dataset in which the specified entities are keys, and values are an association of property names and entity-property values
- The following annotations can be used in the second argument of EntityValue[property,annotation]:
"Description" a brief textual description of the property
