Where 3546 fits
Why 3546 is special
Server Name Indication comes from here, which is what allows many sites to share one address, and which also reveals in clear text which site is being visited.

MMMDXLVI uses the subtractive pair XL: ten before fifty — fifty minus ten.

In historical numeral systems
Egyptian
3 lotuses, 5 coils of rope, 4 hobbles, 6 strokes
3 × 1,000 + 5 × 100 + 4 × 10 + 6 × 1 = 3,546. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
5 corner wedges + 9 vertical wedges (sixties place), 6 vertical wedges (units place)
59 × 60 + 6 = 3546. 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 3546 defined TLS extensions including Server Name Indication, enabling name-based virtual hosting over TLS. SNI is transmitted before encryption is established and is therefore observable.

Common questions
Is 3546 a prime number?
No, 3546 is not prime.

The factors of 3546 are 1, 2, 3, 6, 9, 18, 197, 394, 591, 1182, 1773, 3546.
What is 3546 in Roman numerals?
3546 in Roman numerals is MMMDXLVI. XL is subtractive: ten before fifty — fifty minus ten. Written additively it would be MMMDXXXXVI, which Roman inscriptions used freely — the strict subtractive form is a later convention.
