Why 3492 is special

It encodes internationalised domain names into ASCII, and the resulting homograph confusion — a Cyrillic letter that looks Latin — is why browsers display some domains in encoded form.

Read as powers of two: 2,048 + 1,024 + 256 + 128 + 32 + 4 = 3,492.

In historical numeral systems

Egyptian

3 lotuses, 4 coils of rope, 9 hobbles, 2 strokes

3 × 1,000 + 4 × 100 + 9 × 10 + 2 × 1 = 3,492. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.

Babylonian

5 corner wedges + 8 vertical wedges (sixties place), 1 corner wedge + 2 vertical wedges (units place)

58 × 60 + 12 = 3492. Places are separated by a space on the tablet, with the higher place written first.

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.

Technology & computing

  • RFC 3492 specifies Punycode for encoding Unicode within the limited character set of the domain name system. Visually similar characters across scripts led browsers to adopt display policies for mixed-script names.

Common questions

Is 3492 a prime number?

No, 3492 is not prime.

What is 3492 in Roman numerals?
