Left non-degeneraete cubic solutions to the Yang-Baxter equation

Basic steps:

• construct all shelves up to isomorphism such that the associated solution is cubic.
• construct all solutions up to isomorphism with a given shelf as derived solution.

Count

• all solutions obtained
• all involutive solutions
• all derived solutions

Construct YB semitrusses

Basic steps:

• construct all dervied cubic YB semitrusses
• for each derived cubic YB semitruss, construct all possible lambda-maps
• for each possible lambda-map, construct, if exist, all possible circle operations.
