Why 214 is special

CCXIV uses the subtractive pair IV: one before five — five minus one.
Binary
1 1 0 1 0 1 1 0
1 × 128 + 1 × 64 + 0 × 32 + 1 × 16 + 0 × 8 + 1 × 4 + 1 × 2 + 0 × 1 = 214
Octal
3 2 6
3 × 64 + 2 × 8 + 6 × 1 = 214
Hexadecimal
d 6
d × 16 + 6 × 1 = 214
Read as powers of two: 128 + 64 + 16 + 4 + 2 = 214.
In historical numeral systems
Egyptian
2 coils of rope, 1 hobble, 4 strokes
2 × 100 + 1 × 10 + 4 × 1 = 214. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
3 vertical wedges (sixties place), 3 corner wedges + 4 vertical wedges (units place)
3 × 60 + 34 = 214. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
sigma, then iota, then delta, marked as a numeral
sigma-iota-delta + keraia
sigma + iota + delta written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
resh, then yod, then dalet
resh-yod-dalet
resh (200) + yod (10) + dalet (4) = 214, written in descending order.
Maya
2 bars (upper, twenties place) over 2 bars + 4 dots (lower, units place)
10 × 20 + 14 = 214. 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.

The Kangxi Dictionary of 1716 organised characters under 214 radicals. The system remains the basis of character lookup in many Chinese and Japanese dictionaries, despite later simplification of the characters themselves.
