摘要：

The Gersten group G is the split extension F-3 (sic)(phi) Z of the free group F-3 with basis {a, b, c} by the automorphism phi : a bar right arrow a, b bar right arrow ba, c bar right arrow ca(2). We describe the generators and structure of the group Out(G) and prove that Out(G) similar or equal to (F-3 x Z(3)) (sic) (Z(2) x Z(2)).
