Where 322 fits
Why 322 is special
The Lucas sequence follows the same rule as Fibonacci from a different start, and the two are deeply linked: Lucas numbers are sums of Fibonacci neighbours. The golden ratio governs both.

1 × 256 + 0 × 128 + 1 × 64 + 0 × 32 + 0 × 16 + 0 × 8 + 0 × 4 + 1 × 2 + 0 × 1 = 322

5 × 64 + 0 × 8 + 2 × 1 = 322
Hexadecimal

1 × 256 + 4 × 16 + 2 × 1 = 322
Read as powers of two: 256 + 64 + 2 = 322.
In historical numeral systems
Egyptian
3 coils of rope, 2 hobbles, 2 strokes
3 × 100 + 2 × 10 + 2 × 1 = 322. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
5 vertical wedges (sixties place), 2 corner wedges + 2 vertical wedges (units place)
5 × 60 + 22 = 322. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
tau, then kappa, then beta, marked as a numeral
tau-kappa-beta + keraia
tau + kappa + beta written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
shin, then kaf, then bet
shin-kaf-bet
shin (300) + kaf (20) + bet (2) = 322, written in descending order.
Maya
3 bars + 1 dot (upper, twenties place) over 2 dots (lower, units place)
16 × 20 + 2 = 322. 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.

Mathematics
Lucas numbers use Fibonacci's rule starting 2, 1 instead of 1, 1, and each is the sum of the Fibonacci numbers either side of it. Both converge on the golden ratio at the same speed.
