You cannot swap FIFIR and RUBIA because the letter R is upside down.
I don't think that happens in the alternative solution.
Describing it accurately is hard, so here's a link to what it looks like: https://imgur.com/gcIZnre |

"Two L or I pentominoes cannot fit entirely in 2 x 5 and 5 x 2 rectangles." This is automatically implied by the immediately preceding statement. So it should be removed to avoid confusion
It is not. In the example, this rule prevents swapping the leftmost L with the bottommost I, because then the first two columns would form a 5x2 rectangle that is filled with two I pentominoes and nothing else |

Country : France | Hello everybody. Problem 6 - Azure and rose journey:
I dont understand the scheme L1 R2 L3 R1 L2 R3 L1... If letters L and R are for colours, is L for Azure (why?) and R for Rose, or is it possible to begin with Rose? |
