关于是否有抄老外的大菠萝研究
中国开创六大实心系列满握在手
龚永明编写
此篇之研究终于一扫日本“大宝塔、日本晶体”之昔日霸风,开创中国智慧榫卯在大菠萝领域中的珍贵地位,民族之复兴国之瑰宝将在巍巍中华,屹立东方。 华夏大地地大物博,孕育出了实心大菠萝璀璨夺目的文化。
关于是否有抄老外的大菠萝,请看这段文字:Japanese Pagoda (or Crystal) Burrs
These interlocking puzzles are examples of "Pagoda" or "Japanese Crystal" burrs. (Note that the Tower of Hanoi puzzle is sometimes called the Pagoda puzzle, and there are also Kumiki Pagoda puzzles - but here we're talking about another class of burr.) The Pagoda Burr design is easily scalable - the simplest has only three pieces. Larger versions then have 9, 19, 33, 51, 73, 99, and 129 pieces. In general, the nth degree pagoda requires 2n2+1 pieces.
At the Cleverwood site, they say that the 129 piece is rarely produced since it is considered too difficult. I have not seen any order 9 or 10 (163 or 201 piece) Pagoda puzzles.
Order 'n' 1 2 3 4 5 6 7 8 9 10
Edge Length 2 3 4 5 6 7 8 9 10 11
Pieces 2n2+1 3 9 19 33 51 73 99 129 163 201
You can see the pieces for several sizes of Pagoda puzzle at Ishino's Puzzle Will Be Played... website.
A nineteen-piece Pagoda (and a similar 15-piece puzzle) are described in Wyatt's 1928 Puzzles in Wood on pages 33-37. Plans for a 51-piece Japanese Crystal are given in van Delft and Botermans' 1978 Creative Puzzles of the World on pages 77-79. Slocum and Botermans describe The Great Pagoda puzzle in their 1986 book Puzzles Old and New on page 73.
