Where 17,043 fits
Why 17,043 is special
Laboratories are sent identical unknown samples and their answers compared, which is the only practical way to detect a laboratory that is quietly wrong.

1 × 10,000 + 7 × 1,000 + 4 × 10 + 3 × 1 = 17,043. 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.
