Where 3435 fits
Why 3435 is special
3³ + 4⁴ + 3³ + 5⁵ = 3,435. Only 1 and 3,435 do this in base ten, and the list is complete — a two-member sequence that is fully proven rather than merely unextended.

In historical numeral systems
Egyptian
3 lotuses, 4 coils of rope, 3 hobbles, 5 strokes
3 × 1,000 + 4 × 100 + 3 × 10 + 5 × 1 = 3,435. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
5 corner wedges + 7 vertical wedges (sixties place), 1 corner wedge + 5 vertical wedges (units place)
57 × 60 + 15 = 3435. Places are separated by a space on the tablet, with the higher place written first.
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.

Mathematics
Raising each digit to its own power and summing gives back the number for only 1 and 3,435 in base ten. The set is proven complete, which makes it one of the shortest closed sequences in recreational number theory.
