I think MF8 139th Sokoban Competition, Extra, is based on Druille + Jordi Domenech version, Tableau 92 b (in the set The Beautiful World of Remodels 2 #58). I publish below the three versions:
- Druille, Tableau 82
- Druille + Jordi Domenech, Tableau 82 b (in The Beautiful World of Remodels 2 #58)
- Druille + 珏 (MF8 139th Sokoban Competition, Extra)
Look especially at the top of the puzzles. Perhaps the credits for this last version could be corrected. Thank you very much.
