Each relation below starts at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.

- Authored annotation
- take path components
Authored explanation
Take based loops as representatives and identify two loops exactly when they are homotopic through based loops. The quotient set of based-homotopy classes is π1, with multiplication induced by concatenation.
How to interpret this relation type
Identify elements by a stated equivalence relation and equip the quotient with the induced structure. The edge detail must state the representatives and equivalence relation.
This is an authored directed relation from the source endpoint to the target endpoint.

- Authored annotation
- iterate loops or map spheres
Authored explanation
Higher homotopy groups are obtained from based maps of spheres, equivalently iterated loop spaces.
How to interpret this relation type
Apply a standard functorial or canonical construction whose output is not merely a reduct of the input and is not generally an equivalent presentation of the same object.
