Where 7518 fits
Why 7518 is special
It names the algorithms the rest of the family may use, including the deliberately narrow set that keeps implementations from negotiating something broken.

Hexadecimal
1 d 5 e
1 × 4,096 + d × 256 + 5 × 16 + e × 1 = 7,518
Read as powers of two: 4,096 + 2,048 + 1,024 + 256 + 64 + 16 + 8 + 4 + 2 = 7,518.
In historical numeral systems
Egyptian
7 lotuses, 5 coils of rope, 1 hobble, 8 strokes
7 × 1,000 + 5 × 100 + 1 × 10 + 8 × 1 = 7,518. 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.
