Where 11,801 fits
Why 11,801 is special
It is why network sockets in an office are wired to a category rather than to a specific application, so the same cable serves telephony, Ethernet and whatever replaces them.

1 × 10,000 + 1 × 1,000 + 8 × 100 + 1 × 1 = 11,801. 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.
