摘要
For any arbitrarily large m(e.g., m = 1000000) natural number, a set of m benzenoid systems with the same number vertices have been found so that every pair of them possesses the same Randic index, but no two of them exist with the same modified Zagreb M*(2) index, on the other hand, another set of m benzenoid systems with the same number vertices have also been discovered so that every pair of them have the same the modified Zagreb M*(2) index, but any two of them don't possess the same Randic index.
