Hoffman's packing puzzle

... that it is possible to pack 27 equal cuboids (pictured) into a cube? Any one of the references of the article supports this basic description of the puzzle; the most widely accessible of the references is https://johnrausch.com/PuzzleWorld/puz/hoffmans_packing_puzzle.htm, although the sentence in the article that most clearly supports the hook ("Its goal is to assemble ...") instead uses two book sources. Also, to forestall pedantry: the more technically correct word would be "congruent" rather than "equal", but I think "equal" conveys the meaning accurately enough while being more accessible. I also thought about using "identical" but the blocks in the image are obviously not identical even at 100px (they have different colors).

Article is new enough, long enough, and well cited. Hook is interesting and supported by cited sources. QPQ is done. No copyvio detected. Image is freely licensed. Good to go. -Zanhe (talk) 05:28, 19 November 2019 (UTC)
