Where 7541 fits
Why 7541 is special
It was designed specifically to resist the compression side-channel that broke the previous approach, where response size leaked secrets.

7 × 1,000 + 5 × 100 + 4 × 10 + 1 × 1 = 7,541. 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.
