摘要
We generalize the main result of arXiv:2505.17960 and show the consistency of the statement ``There are exactly n Q-points up to isomorphism"for any finite n. Furthermore, we show that the above statement for n=2 can alternatively be obtained by a length-ω2 countable support iteration of Matet-Mathias forcing restricted to a Matet-adequate family.
