We develop lower bounds for the spectral radius of symmetric, skew-symmetric, and arbitrary real matrices, Our approach utilizes the well-known Leverrier-Faddeev algorithm for calculating the coefficients of the characteristic polynomial of a matrix in conjunction with a theorem by Lucas which state

A method for the estimation of E,,, the number of benzenoid systems with h hexagons, is presented. B,, is predicted to lie between 3.200x lo6 and 3.202x 106. This is a significant improvement on the earlier result which located BI1 between 3.080~ lo6 and 3.300x 106.
