Unmatter combinations as pairs of quarks (q) and antiquarks (a), for q >= 1 and a >= 1. Each combination has n = q+a >= 2 quarks and antiquarks which preserve the colorless. - if n = 2, we have: qa (biquark - for example mesons and antimesons), so the pair is (1,1); - if n = 3 we have no unmatter combination, so the pair is (0,0); - if n = 4, we have qqaa, the pair is (2,2); - if n = 5, we have qqqqa, qaaaa, so the pairs are (4,1) and (1,4); - if n = 6, we have qqqaaa, whence (3,3); - if n = 7, we have qqqqqaa, qqaaaaa, whence (5,2),(2,5); - if n = 8, we have qqqqqqqa, qqqqaaaa, qaaaaaaa, whence (7,1),(4,4),(1,7); - if n = 9, we have qqqqqqaaa, qqqaaaaaa, whence (6,3),(3,6); - if n = 10, we have qqqqqqqqaa, qqqqqaaaaa, qqaaaaaaaa, whence (8,2), (4,4), (2,8).
