Why 61,508 is special

Its Safety Integrity Levels are the parent of the automotive ASIL scale, and both express tolerable failure rates rather than a general sense of safety.

6 × 10,000 + 1 × 1,000 + 5 × 100 + 8 × 1 = 61,508. 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.
