Why 6194 is special

Like the MD5 notice, it advises against the algorithm well before the ecosystem stopped using it, which took a demonstrated collision.

In historical numeral systems

Egyptian

6 lotuses, 1 coil of rope, 9 hobbles, 4 strokes

6 × 1,000 + 1 × 100 + 9 × 10 + 4 × 1 = 6,194. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.

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.
