On rational groups with Sylow 2-subgroups of nilpotency class at most 2 %K Rational group %K nilpotency class %K Markel group %R %X A finite group $G$ is called rational if all its irreducible complex characters are rational valued. In this paper we discuss about rational groups with Sylow 2-subgroups of nilpotency class at most 2 by imposing the solvability and nonsolvability assumption on $G$ and also via nilpotency and nonnilpotency assumption of $G$. %U http://bims.iranjournals.ir/article_1113_58118f7c20f56a8f682e23695d8efc9e.pdf
