Question: How to use the group produced with DirectProduct?

I don't know how to use the group produced with DirectProduct. such as

G := DirectProduct(QuaternionGroup(), CyclicGroup(3)):


IsNormal(CyclicGroup(2), DirectProduct(CyclicGroup(2), CyclicGroup(2)))

They all will get error information. It looks like the format is different, do I need to convert it somehow? Or is this a bug in maple?
