We exhibit seven linear codes exceeding the current best known minimum distance d for their dimension k and block length n . Each code is defined over F 8 , and their invariants [n,k,d] are given by [49,13,27] , [49,14,26] , [49,16,24] , [49,17,23] , [49,19,21] , [49,25,16] and [49,26,15] . Our method includes an exhaustive search of all monomial evaluation codes generated by points in the [0,5]×[0,5] lattice square.
