| CCC-1 is a redesign of Stewart Coffin's design #177-A,
called Five Woods.
In 2014, Rob Stegmann found an 'unwanted' solution to the original
design. Not a mathematically correct solution, but one that was
close enough to spur Stewart to modify the design. He tried perhaps
a hundred different piece combinations with 5 pieces and a total
of 25 squares.
Stewart enlisted my aid in trying to find unwanted
solutions to ones he thought might be free of them. I obliged
with my 'throw-and-jiggle' program, which was quite adept at
finding alternate solutions.
CCC-1 is the one we chose as the best.
This was my souvenir puzzle at the 35th International Puzzle Party. |
