      I have only computed with repetitions and I agree with Jack's solutions.
      7 rows, repetition allowed, minimal, sum 30076:
      919 1013 1231 1613 2311 4133 11071
      47 109 191 349 911 3469
      31 41 79 281 1279
      5 19 101 499
      7 41 199
      17 79
      31
      8 rows, repetition allowed, minimal, sum 206282:
      1087 1181 1543 2309 3727 6701 19543 93077
      47 181 383 709 1487 6421 36767
      67 101 163 389 2467 15173
      17 31 113 1039 6353
      7 41 463 2657
      17 211 1097
      97 443
      173
      Guess whether I'm using a computer :-)
