Where 5661 fits
Why 5661 is special
Its parallel NFS extension lets a client read data directly from storage servers rather than through one head, which is what removed the single bottleneck.

5 × 1,000 + 6 × 100 + 6 × 10 + 1 × 1 = 5,661. 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.
