How do you set up a seven-player game on the six-to-eight-player map?

Question

Accepted Answer

Either side of the six-to-eight-player map can be the six-player or eight-player side; the players choose. No side is preferred for seven players. The recommended split is the four-player one, with three-player West and five-player East, because flipping it leaves Cthulhu with many areas alone.
