Where 130 fits
Why 130 is special
It is the longest continuous military aircraft production run in history, and it can operate from a dirt strip that no jet transport could use.

Read as powers of two: 128 + 2 = 130.
In historical numeral systems
Egyptian
1 coil of rope, 3 hobbles
1 × 100 + 3 × 10 = 130. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
2 vertical wedges (sixties place), 1 corner wedge (units place)
2 × 60 + 10 = 130. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
rho, then lambda, marked as a numeral
rho-lambda + keraia
rho + lambda 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 lamed
qof-lamed
qof (100) + lamed (30) = 130, written in descending order.
Maya
1 bar + 1 dot (upper, twenties place) over 2 bars (lower, units place)
6 × 20 + 10 = 130. 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.
