In a royal dynasty, there are eight brothers. The present king is the eldest brother. As a rule, a brother will come to the throne when he is the oldest of those alive. However, there is a curse on the dynasty: whenever each of three successive brothers comes to the throne, the following brother will die from despair. In how many different ways may the brothers rule? (Only the set of those coming to throne matters.)
