Why 768 is special

It is three pages long and deliberately guarantees nothing, which is exactly why DNS, video calls and games are built on it rather than on TCP.

3 × 256 + 0 × 16 + 0 × 1 = 768

Read as powers of two: 512 + 256 = 768.

In historical numeral systems

Egyptian

7 coils of rope, 6 hobbles, 8 strokes

7 × 100 + 6 × 10 + 8 × 1 = 768. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.

Babylonian

1 corner wedge + 2 vertical wedges (sixties place), 4 corner wedges + 8 vertical wedges (units place)

12 × 60 + 48 = 768. Places are separated by a space on the tablet, with the higher place written first.

Greek (Ionic)

psi, then xi, then eta, marked as a numeral

psi-xi-eta + keraia

psi + xi + eta written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.

Hebrew numerals

tav, then shin, then samekh, then het

tav-shin-samekh-het

tav (400) + shin (300) + samekh (60) + het (8) = 768, written in descending order.

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.
