Pentatwig
Puzzles
These puzzles use the 12 pentatwigs.
The pieces cover 60 unit line segments.
Geometric Forms
Pairs & Triplets
Use all the
pieces to make two or three identical copies of a pattern. 


Compatibilities
Polyforms are compatible if
there is a shape that can be tiled by each. You can find more about
Polyform Compatibility at George Sicherman's Polyform Curiosities website.
Here are minimal known compatibilities for the pentatwigs.

tritwigs and tetratwigs, all found by George 
Baiocchi Figures
A
Baiocchi Figure is one with maximal symmetry for
the set of polyforms. You can find more about
