%N Triangle read by rows: T(n,k) = number of tournaments with n players which have the k-th score sequence. The score sequences are in the same order as A068029 and start with the empty score sequence.

%C The score sequences are sorted by number of players and then lexicographically.

%C There are A000571(m) score sequences for m players. The sum of all the a(n) for m players is A006125(m)=2^(m(m-1)/2).

%e There are two score sequences with 3 players: [0,1,2] from 6 tournaments and [1,1,1] from 2 tournaments. These score sequences come 4th and 5th respectively, so a(4)=6 and a(5)=2.

%Y Cf. A000571, A006125, A068029, A125031 (number of highest scorers), A123553.

%Y Other sequences that can be calculated using this one: A013976, A125031.
