|From 1987 to 1990 I ran a computer analysis of all
6-piece burrs. Several of the designs discovered were
chosen as 'best' and made for sale. This souvenir was
chosen as one of the better designs from the analysis that
has not previously been made.
The solution requires 8 moves to remove the first piece.
There are a variety of disassembly sequences for level-8
6-piece burrs, showing that when looking for an interesting high-level
6-piece burr, 'eight is enough'.
This was my souvenir puzzle at the 29th International Puzzle Party.
