It holds for all n>=1 that a(n) = A213724(A179016(n-1))-A179016(n), meaning that a(n) = 1 when the next node upwards in the infinite trunk of beanstalk sequence (A179016) is the smaller of the two possible branches from A179016(n), and 0 when it is the larger of the said branches. That is, this sequence tells whether A179016 proceeds "left" or "right" at each step.
