[Retros] How many times could a Diagram be repeated during aproofgame?

[Francois Labelle]

I'm trying to correct the calculations of Yefim and Guus:

Number of repeated diagrams:

5 (castling rights) * 2 (repetition) * 2 (whose turn)
+ 1 (en passant, must be the initial position)
+ 1 (repeat one position 3 times)
= 22

Number of moves necessary:

5 (castling rights) * (2 + 2.5 + 2)
(moves for: repetition, turn change, repetition)
+ 4 (castling right changes) * 2 (moves per castling right change)
+ 2 (moves for en passant)
+ 2 (moves to repeat one position 3 times)
= 44.5 ...which is fortunately less than 50 moves.

Feel free to correct me!
