Where 4066 fits
Why 4066 is special
It switches analogue signals under digital control, which is how a mixing desk or a synthesiser routes audio without a mechanical switch in the path.

4 × 1,000 + 6 × 10 + 6 × 1 = 4,066. 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.
