The slabs
made a most intricate and fascinating design,
but a thoroughly unobtrusive one, unless one paid deliberate
attention to it.

Polyiamond Hexagon Tiling. Tile a straight or ragged hexagon with various polyiamonds. | |

Hexiamond Triplets. Arrange the 12 hexiamonds to form three congruent polyiamonds. | |

Tiling a Triangle with Similar Polyaboloes. Join variously sized copies of a polyabolo to make a triangle. | |

Tiling an Octagon with Similar Polyaboloes. Join variously sized copies of a polyabolo to make an octagon. | |

Tiling a Home Plate Hexabolo with Similar Polyaboloes. Join variously sized copies of a polyabolo to make a home plate. | |

Polydrafter Irreptiling. Tile a polydrafter with smaller copies of itself, not necessarily equal. | |

Bireptiles. Dissect two joined copies of a polyform into equal smaller copies. | |

Similar Hexiamond Figures, 2–2–8. With the 12 hexiamonds, make three similar figures, one at double scale. | |

Pentacubes in a Box Without Corners. Join copies of a pentacube to make a rectangular prism with its corner cells removed. | |

Polycube Reptiles. Join copies of a polycube to make a larger copy of itself. | |

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. | |

3^{3} + 4^{3}
+ 5^{3} = 6^{3}.
Dissect a cube of side 6 to make cubes of sides 3, 4, and 5. | |
