Supercomputer simulations are performed in order to reveal characteristic features of vector fractons excited on very large two-dimensional percolating networks. It is found that the frequency region of the crossover from vector to scalar fractons in the density of states is rather broad. It is also confirmed that the vector fracton dimensionality \ ildeD is close to 0.79, in accord with the scaling prediction.
