摘要：
We investigate which real flag manifolds of the form have the -cup-length equal to the dimension. We obtain a complete classification of such manifolds of the form and . Additionally, we provide an infinite family of manifolds which give the negative answer to a question from J. Korba and J. Lorinc [5].
