| BoundaryMap(C)Inputs a resolution, chain complex or cochain complex C and returns the function C!.boundary. | 
| BoundaryMatrix(C,n)Inputs a chain or cochain complex C and integer n>0. It returns the n-th boundary map of C as a matrix. | 
| Dimension(C) Dimension(M) Inputs a resolution, chain complex or cochain complex C and returns the function C!.dimension . Alternatively, inputs an FpG-module M and returns its dimension as a vector space over the field of p elements. | 
| EvaluateProperty(X,"name") Inputs a component object X (such as a ZG-resolution or chain map) and a string "name" (such as "characteristic" or "type"). It searches X.property for the pair ["name",value] and returns value. If X.property does not exist, or if ["name",value] does not exist, it returns fail. | 
| GroupOfResolution(R)Inputs a ZG-resolution R and returns the group G. | 
| Length(R)Inputs a resolution R and returns its length (i.e. the number of terms of R that HAP has computed). | 
| Map(f)Inputs a chain map, or cochain map or equivariant chain map f and returns the mapping function (as opposed to the target or the source of f) . | 
| Source(f)Inputs a chain map, or cochain map, or equivariant chain map, or FpG-module homomorphism f and returns it source. | 
| Target(f)Inputs a chain map, or cochain map, or equivariant chain map, or FpG-module homomorphism f and returns its target. |
