Braille Dice

Six-dot braille has a total of 64 combinations (including the blank pattern). If braille cells that can be rotated into each other are treated as identical—for example, ⠋ (dots 1-2-4) and ⠴ (dots 3-5-6)—the set reduces to 36 unique patterns.
Based on these 36 patterns, a set of six dice can be designed: each die has six faces, and the six dice together cover all 36 combinations. By rotating the dice, all pattern orientations can be displayed.
To avoid the need for print-support structures, there is also a seven-die version. In this design, the bottom face of each die is left blank, so 7 dice × 5 faces = 35 patterns, and together with the blank pattern, the total still reaches 36, covering all variations.
