We show that every innite discrete group G has an innite minimal subow in its Bernoulli ow f0; 1g G. A countably innite group G has an eective minimal subow in f0; 1g G. If G is countable and residually nite then it has such a subow which is free. We do not know whether there are groups G with no free subows in f0; 1g G.
