We present the tables of feasible parameters of primitive $3$-class Q-polynomial association schemes and $4$- and $5$-class Q-bipartite association schemes (on up to $2800$, $10000$, and $50000$ vertices, respectively), accompanied by a number of nonexistence results for such schemes obtained by analysing triple intersection numbers of putative open cases.
