# Polyform Tiling

The slabs made a most intricate and fascinating design, but a thoroughly unobtrusive one, unless one paid deliberate attention to it.
—Carlos Castaneda, The Second Ring of Power
The tiling problem is to join copies of one or more polyforms to make a given polyform.

Join two copies of a polydrafter, then dissect the result into equal smaller copies of it. The Didrafter Fish. Form a compact shape with the 13 proper and extended didrafters. Scaled Polydrafter Tetrads. Join four similar polydrafters so that each borders the other three. Convex Figures with Didrafter Pairs. Make a convex polydrafter with copies of two didrafters. Convex Figures with Didrafter Triplets. Make a convex polydrafter with copies of three didrafters. Convex Shapes from the 13 Didrafters. Make a convex polydrafter with the 13 didrafters. Rectangles Tiled with Three Didrafters. Make a rectangle with copies of three didrafters. Regular Hexagons Tiled with Three Didrafters. Make a regular hexagon with copies of three didrafters. Making a Rectangle from Different Didrafters. Make a rectangle out of up to eight distinct didrafters. Didrafters at Scales 1 and 5. Arrange a double set of the 13 didrafters to form copies of a didrafter at scales 1 and 5. Inflated Didrafters. Form a convex shape with the 13 didrafters after expanding some at integer scales or scales of an integer times √3. Convex Figures with Tridrafter Pairs. Make a convex shape with copies of two tridrafters. Galaxies from the 14 Tridrafters. Join the 14 proper tridrafters to make a shape with 6-rotary symmetry. Stelo Twins and Triplets. Use Jacques Ferroul's Stelo pieces to make multiple copies of the same shape.

### Polydoms

 Kiteless Didoms. Form shapes with the set of 12 didoms, omitting the kite didom. Scaled Polydom Tetrads. Join four similar polydoms so that each borders the other three. A Counterexample To Livio Zucca's Island Conjecture. Make a polydom island in the shape of a polyomino that cannot be tiled with dominoes. Convex Figures with Didom Pairs. Make a convex polydom with copies of two didoms. Convex Figures with Didom Triplets. Make a convex polydom with copies of three didoms. Convex Shapes from the 13 Didoms. Make a convex polydom with the 13 didoms, including the Kite Didom. Inflated Didoms. Make a convex polydom with the 13 didoms, including the Kite Didom, enlarging some. Tiling the Owen Dodecagon With Three Didoms. Make an almost regular dodecagon with copies of the 13 didoms.

### Various

 Contiguous Partridge Tilings. Use 1 shape at scale 1, 2 at scale 2, and so on up to n at scale n, to form a scaled copy of the shape in which equal tiles are contiguous. Contiguous Reverse Partridge Tilings. Use 1 shape at scale n, 2 at scale n−1, and so on up to n at scale 1, to form a scaled copy of the shape in which equal tiles are contiguous. Lovebirds Tilings. Use 2 copies of a shape at scale 1, 4 at scale 2, and so on up to 2n at scale n, to form two scaled copies of the shape.

## Solid Tiling

 Pentacubes in a Box. Join copies of a pentacube to make a rectangular prism. Prime Boxes for the Clip Pentakedge. Identify the irreducible boxes that can be tiled by the Clip Pentakedge. Pentacubes in a Box Without Corners. Join copies of a pentacube to make a rectangular prism with its corner cells removed. Pentacubes in a Box With Four Edges Removed. Join copies of a pentacube to make a rectangular prism from which the cells along four parallel edges have been removed. Pentacubes in a Box With All Edges Removed. Join copies of a pentacube to make a rectangular prism from which the cells along the edges have been removed. Polycube Reptiles. Join copies of a polycube to make a larger copy of itself. Polycube Bireptiles. Join two copies of a polycube, then dissect the result into equal smaller copies of it. Proper Minimal Polycube Irreptiles. Join variously sized copies of a polycube to make a larger copy of itself, using fewer copies than would be needed if they were all the same size. 33 + 43 + 53 = 63. Dissect a cube of side 6 to make cubes of sides 3, 4, and 5. Tiling a Solid Diamond Polycube With Right Tricubes. Dissect an octahedron-shaped polycube into L-shaped tricubes.

Use a pentacube to tile various pentacubes scaled up by 2 or 3. Prisms with Square-Symmetric Bases from the 29 Pentacubes. Use all 29 pentacubes to form a prism whose base is a fully-symmetric 29-omino.
