On Rota's problem about \(n\) bases in a rank \(n\) matroid
Partial results are presented to the following problem: Does there always exists an \(n \times n\) matrix (for a set on \(n\) not necessarily distinct bases of a rank \(n\) matroid) so that the \(i\)th column of the matrix consists of the elements of the \(i\)th base and the rows are bases as well.
