Where 7404 fits
Why 7404 is special
Six inverters in one package is the most-used part in the logic family, because almost every circuit needs a signal flipped somewhere.

In historical numeral systems

7 lotuses, 4 coils of rope, 4 strokes
7 × 1,000 + 4 × 100 + 4 × 1 = 7,404. 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.
