Abstract
In this paper we solve the problem of group classification of the (1+1)-dimensional fourth-order linear evolution equations of the most general form. We prove that there are three, six and one inequivalent fourth-order linear evolution equations that admit two-, three-, and four-dimensional symmetry algebras, respectively.
