%e A381187 For n = 8 there are three 8-tuples with sum A380887(8) = 1089 and product 100^7 * 1089, namely (110, 125, 125, 125, 128, 150, 150, 176), (120, 125, 125, 125, 125, 128, 165, 176), (121, 125, 125, 125, 125, 128, 160, 180). The first of these is the lexicographically smallest and thus is row 8 of the triangle.
