Why 826 is special

The UK's ISO letter code is GB rather than UK, a mismatch that causes recurring problems in software. The numeric code avoids the question entirely.

In historical numeral systems

Egyptian

8 coils of rope, 2 hobbles, 6 strokes

8 × 100 + 2 × 10 + 6 × 1 = 826. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.

Babylonian

1 corner wedge + 3 vertical wedges (sixties place), 4 corner wedges + 6 vertical wedges (units place)

13 × 60 + 46 = 826. Places are separated by a space on the tablet, with the higher place written first.

Greek (Ionic)

omega, then kappa, then stigma, marked as a numeral

omega-kappa-stigma + keraia

omega + kappa + stigma 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 tav, then kaf, then vav

tav-tav-kaf-vav

tav (400) + tav (400) + kaf (20) + vav (6) = 826, 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.
