Query: Lower bound for Buchstaber invariants of real universal complexes   In this article, we prove that Buchstaber invariant of 4-dimensional real
universal complex is no less than 24 as a follow-up to the work of Ayzenberg
and Sun. Moreover, a lower bound for Buchstaber invariants of $n$-dimensional
real universal complexes is given as an improvement of result of Erokhovets.
