OLYMPIAD OF METROPOLISES, Moscow, September 2, 2019 · 2 септември 2019 г.

Условие

You are given a regular octahedron without walls — only edges and vertices. Each edge is made of a conductor of same electric resistance equal to 12 ohm. Find the resistance between two nearest vertices.

The answer should be given in the SI units unless otherwise stated. If the numerical result turns out to be an integer, it should be given as the answer. Otherwise round the result to the first decimal. $g = 10\ \mathrm{m/s^2}$.
