    Let pnp_n denote the nthn^{\text{th}} prime number and define an=⌊pnν⌋a_n=\lfloor p_n \nu \rfloor, where ν\nu is a positive irrational number. Is it possible that there exist only finitely many kk such that (2akak)\binom{2a_k}{a_k} is divisible by pi10p_i^{10} for all i=1,2,…,2020i=1,2,\ldots, 2020?
