Where 770 fits
Why 770 is special
A zip bomb is this weakness: a small input that the receiving system expands until it exhausts memory or disk.

Read as powers of two: 512 + 256 + 2 = 770.
In historical numeral systems
Egyptian
7 coils of rope, 7 hobbles
7 × 100 + 7 × 10 = 770. 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), 5 corner wedges (units place)
12 × 60 + 50 = 770. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
psi, then omicron, marked as a numeral
psi-omicron + keraia
psi + omicron 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 ayin
tav-shin-ayin
tav (400) + shin (300) + ayin (70) = 770, 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.
