Where 9147 fits
Why 9147 is special
It reduces the handshake and adds record number encryption, which matters because a datagram's headers are visible to anyone on the path.

Read as powers of two: 8,192 + 512 + 256 + 128 + 32 + 16 + 8 + 2 + 1 = 9,147.
In historical numeral systems
Egyptian
9 lotuses, 1 coil of rope, 4 hobbles, 7 strokes
9 × 1,000 + 1 × 100 + 4 × 10 + 7 × 1 = 9,147. 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.
