James Malcom: Is this the length record for 32 units? (2021-02-16)
A.Buchanan: Isn’t there a length record catalogue by Alain Brobecker? (2021-02-17)
A.Buchanan: http://abrobecker.free.fr/chess/lengths.pdf (2021-02-18)
James Malcom: I do not find this in there. (2021-02-18)
A.Buchanan: Yes, I see now. I had thought that Alain's paper was comprehensive for its time, but I guess not. The "Number of last moves" space is a good candidate to be put in a PDB page, like the "first move" page. That's pretty easy to do, based on the structure that Alain has given, but some scholarship is required first to validate what the last records are 10 years on, for the different cases. For example there's Thierry Le Glueher's extensions of Gyula Breyer's stupendous matrix. Those are already in PDB. Should also reach out to the Usual Suspects to ask what they've done which should be included. I don't think that Alain is active in this particular area right now. Any volunteers to own it? :) I have too much going on right now to own this, but I am happy to support e.g. by searching WinChloe, proof-reading etc. There are some magnificent problems here: this is worth doing.

Nikolai Beluhov: Throughout the game, three different positions had to be repeated two times each (with the other side on the move) in order for the position to be formed.
The theme of loss-of-tempo-motivated position repetition was deeply explored by Luigi Ceriani (1894-1969) and is present in many of his works, including numerous ortho-reconstructions.
I only know of two twofold implementations: P1183992 by Ceriani himself (possibly a version by N. Plaksin or A. Kuznetsov of P0002948) and P0005418 by S. Volobuev (with a "#1" stipulation which determines the side to move in the diagram position). D. Baibikov's problem presents the first ever threefold implementation. (2011-01-02)
A.Buchanan: “fake game array” (FPI) is another special case of Ceriani’s player inversion (2021-02-24)
A.Buchanan: This is a wonderful problem. The repeated diagrams are where wDb8 & sLb7. There are sequences e.g. n. Db8~ Lb7-c8 (*) n+1. Dd8-b8 La8-b7 n+2. Dc8-d8 Lb7-a8 n+3. Db8-c8 (*) La8-b7. Need to ensure that over this sL shifts from c8 to a8, otherwise there are unnecessary additional repeated diagrams. Have fixed the solution given above. (2021-02-24)
A.Buchanan: “Position” is diagram + the move + castling rights + e.p. status. What is repeated is a diagram. Given that the stipulation was in Russian originally, I dare to change the stipulation here... (2021-02-25)

La Genesi delle Posizioni 1961
(13+12)
Were any diagrams repeated during the game?
Nikolai Beluhov: This problem was published as a part of the Shakhmaty v SSSR 1977 New Year solving tourney. It is probably a version of P0002948 (Luigi Ceriani, La Genesi delle Posizioni, 1961, N49), even though I think that the CPDB diagram for the last problem must contain some typo.
Throughout the game, two different positions had to be repeated two times each (with the other side on the move) in order for the position to arise. Compare P0005418 (S. Volobuev, Thèmes-64, 1986) as well as the threefold implementation in P1183971 (D. Baibikov, Schachmatnaja komposizija, 2010). (2011-01-02)
