A new approach to maturity of molecules by rationality of finite groups

These two concepts, maturity in chemistry and rationality in group theory were discovered by a chemist, Fujita. In the present study, we introduce a new approach to maturity and immaturity of simple groups, using the deep theorem (Feit and Seitz in Ill J Math 33:101–131, 1988). Additionally, we prove that 1,3,5-trimethyl-2,4,6-trinitrobenzene are always unmatured and tetra platinum(II) with point group $D_{2n}$ , dihedral group of order $2n$ , is unmatured if $nne 1,2,3,4,6$ . Also, we compute integer-valued characters of the simple sporadic group $Ly$ .
