Where 8586 fits
Why 8586 is special
By convention climbers stop a few metres short of the true summit, honouring a promise made to the Sikkimese authorities in 1955 that the top would remain untrodden. Almost every ascent since has kept it.

8 × 1,000 + 5 × 100 + 8 × 10 + 6 × 1 = 8,586. 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.

Kangchenjunga's first ascent party stopped short of the actual summit at the request of local authorities, and the convention has held for seventy years. It is the only major peak where the top is routinely not stood on.
