Where 11,770 fits
Why 11,770 is special
Most cryptographic failures in practice are key management failures, and this is the standard that treats key handling as its own discipline.

1 × 10,000 + 1 × 1,000 + 7 × 100 + 7 × 10 = 11,770. 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.
