N2 - We study the group Autc(R) of computable automorphisms of the linear order of the reals. It is shown that this group shares several common properties with the group Autc(Q) of computable automorphisms of the rationals: they both are not divisible and each of them has exactly three nontrivial normal subgroups. Each of these groups contains an element that is not conjugate with its square. However, Autc(R) also possesses properties that are not present in Autc(Q): Autc(R) contains a bump that is not conjugate with its square and, for every c.e. real z, Autc(R) contains a bump with upper boundary point z.
