In hit.two_quotient we define a general construction to define hits with 2-dimensional path constructors, similar to quotients. We can add 2-paths between any two 'words', where a word consists of 1-path constructors, concatenation and inverses. We use this to define the torus, reflexive quotients and the reduced suspension. There is still one 'sorry' in the construction |
