1: 1
2: 1 1
3: 2 1 1
4: 3 2 3 2
5: 6 5 5 5 5
6: 14 12 12 14 12 12
7: 34 33 33 33 33 33 33
8: 98 94 96 94 98 94 96 94
9: 294 290 290 293 290 290 293 290 290
10: 952 949 949 949 949 952 949 949 949 949
T(6,3)=12 because there are 12 standard Young tableaux with 6 boxes and a major index equivalent to 3 modulo 6.
