Back in my blog's first year, I asked if it was possible to make a certain tiling of a pair of tetromino sets with a monomino hole such that the edges of the polyominoes could be tiled by the 16 tetrasticks. At #G4G15, William Waite gave me a puzzle using both polyominoes and polyedges that he said was inspired by a conversation we'd had about the possibility of a combined polyedge/polyomino tiling puzzle. (That puzzle uses a simpler and easier to tile set of pieces.)
Lately, I've been realizing that Jaap Scherphuis' PolySolver is capable of solving a lot of problems I didn't have another way to solve, so I tried it on this one. It turns out that there is a unique solution! (Unfortunately, no solution with the monomino in the center, as I'd hoped.)
Slowly getting through my backlog of emails and tasks that built up while I was away for #G4G15. It was an extended trip this time, but #G4G was fabulous.
