There are no free elections in the country, and three economic workshops will have to choose the ruling force at a closed meeting:

Arms Dealers

Steel Dealers

Human Traffickers

The Arms Dealers' Workshop proposes the following voting rule: starting with player 1, each player successively vetoes one of the unrejected candidates. The only one remaining is considered elected. They propose to keep the right of player 1, because, according to them, in the long run it does not matter much. The preference for choosing one or another candidate satisfies the following condition:

workshops: u = (u1, u2, u3),

parties: Xi = {a, b, c, d},

where

u1 - Arms Dealers,

u2 - Steel Dealers,

u3 - Human Traffickers

and

a - War Party,

b - Control Party,

c - Nostalgic Party,

d - National Minority Party.

u1(d) < u1(c) < u1(b) < u1(a),

u2(c) < u2(d) < u2(a) < u2(b),

u3(c) < u3(a) < u3(b) < u3(d).

All three shops are informed about this distribution of preferences.
