4880
RFC 4880 defines the OpenPGP message format.

- Composite
Where 4880 fits
Why 4880 is special
It standardised the format of PGP encrypted mail and signatures so that independent implementations, notably GnuPG, could interoperate.

1 × 4,096 + 1 × 512 + 4 × 64 + 2 × 8 + 0 × 1 = 4,880
Hexadecimal
1 3 1 0
1 × 4,096 + 3 × 256 + 1 × 16 + 0 × 1 = 4,880
Read as powers of two: 4,096 + 512 + 256 + 16 = 4,880.
In historical numeral systems
Egyptian
4 lotuses, 8 coils of rope, 8 hobbles
4 × 1,000 + 8 × 100 + 8 × 10 = 4,880. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
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.

Related numbers & connections
OpenPGP distributes trust across users and X.509 concentrates it in certificate authorities; the two models rarely interoperate.

why?
Strength 0.50, confidence "high".
Technology & computing
RFC 4880 specifies OpenPGP packet formats, key material and signature types. It is the basis of GnuPG and of the web-of-trust model, which distributes trust across users rather than through certificate authorities.
