We consider solutions of the three well problem. These are maps u satisfying tex2html_wrap_inline8 a.e. in tex2html_wrap_inline10 where the tex2html_wrap_inline12 are the diagonal matrices representing the cubic to tetragonal transformation. It is known that such maps can behave rather irregular. Under the additional assumption that the phase sets tex2html_wrap_inline14 are of finite perimeter we conclude that u is locally a function of one variable only. Addendum: accompanying Maple code
