Parameters for which the Griesmer bound is not sharp

We use our results to identify a class of parameters for linear codes for which the Griesmer bound is not sharp. Our theorem generalizes the non-existence results from Maruta [On the achievement of the Griesmer bound, Des. Codes Cryptogr. 12 (1997) 83-87] and Klein [On codes meeting the Griesmer bound, Discrete Math. 274 (2004) 289-297].
