Where 106 fits
Why 106 is special
106 exists because a voice call is not universally usable. It is a teletypewriter service reaching the same police, fire and ambulance dispatch as 000, it is free, and it works without an operator relay. Australia mandated it rather than leaving accessibility to individual carriers, which is why it has a national number of its own.
Same number, different meanings

- Science
Seaborgium was approved while Seaborg was living, which drew objections as a departure from precedent. He had co-discovered ten elements, which is a substantial part of why the objection was overruled.
- Law & regulation
106 reaches the same police, fire and ambulance dispatch as 000, but by text rather than voice, for people who are deaf or have a speech impairment. Australia established it by regulation rather than leaving accessibility to carriers, which is why it occupies a national number of its own instead of a per-provider service.

Binary

Hexadecimal

6 × 16 + a × 1 = 106
Read as powers of two: 64 + 32 + 8 + 2 = 106.
In historical numeral systems
Egyptian
1 coil of rope, 6 strokes
1 × 100 + 6 × 1 = 106. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
1 vertical wedge (sixties place), 4 corner wedges + 6 vertical wedges (units place)
1 × 60 + 46 = 106. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
rho, then stigma, marked as a numeral
rho-stigma + keraia
rho + stigma written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
qof, then vav
qof-vav
qof (100) + vav (6) = 106, written in descending order.
Maya
1 bar (upper, twenties place) over 1 bar + 1 dot (lower, units place)
5 × 20 + 6 = 106. Places stack vertically with the smallest at the bottom, so the upper group is worth twenty times the lower.
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.

Related numbers & connections
Both are national numbers created to route people to the right service rather than the default one: 106 gives deaf and speech-impaired callers in Australia a text path to emergency dispatch, 111 gives callers in Britain a non-emergency medical line. Each exists so that 000 or 999 is not the only door.
