Cyclic function exchange of three Andernach lions, including black-white cycle of first and second halfmoves.
The problem is not computer-tested - I found firstly geometrical pattern and then I discovered, that neither Popeye nor WinChloe are able to test Andernach roselion... I made some partial tests, but I expect that human solvers will find some cooks (for that reason I used as many flights as possible, at the cost of not elegant captures of black queen). In the last solution in WinChloe implementation is possible to capture ROLd2xg5 over LIg5 but I dislike this difference compared to Popeye (it is easy to avoid it anyway, by adding of some pawns or shift the position one file left and adding something to h8).
