Why 1764 is special

One worker could spin eight threads at once and later many more. Hand spinners destroyed the machines, which is a straightforward response to a device that eliminated their livelihood rather than an irrational one.

In historical numeral systems

Egyptian

1 lotus, 7 coils of rope, 6 hobbles, 4 strokes

1 × 1,000 + 7 × 100 + 6 × 10 + 4 × 1 = 1,764. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.

Babylonian

2 corner wedges + 9 vertical wedges (sixties place), 2 corner wedges + 4 vertical wedges (units place)

29 × 60 + 24 = 1764. Places are separated by a space on the tablet, with the higher place written first.

Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.
