Question: how to compute a very large exponent of primitive element?

Hi,all, here is my question: alias(alpha=RootOf(x^32+x^26+x^19+x^15+x^13+x^11+x^9+x^8+x^4+x+1)); and then i want to compute: alpha^12345678987654321; But when I did it in maple, it failed. I think there should be some way to do it. Would you like to help me? Thanks Gepo
