Why 2264 is special
One catalogue number covers two objects that look entirely different, because the designation predates the distinction being drawn.

In historical numeral systems
Egyptian
2 lotuses, 2 coils of rope, 6 hobbles, 4 strokes
2 × 1,000 + 2 × 100 + 6 × 10 + 4 × 1 = 2,264. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
3 corner wedges + 7 vertical wedges (sixties place), 4 corner wedges + 4 vertical wedges (units place)
37 × 60 + 44 = 2264. 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.
