[Retros] T.T : Summary 1

[Nicolas.Dupont at math.univ-lille1.fr]

A good start concerning both the number of entries and their levels.

A/2/16 = (1 kind of matrice)
A/3/22 -
A/4/36 = (1 kind of matrice)
A/6/39 -
A/7/51 -
A/8/57 -
B/15/71 -

The sign = indicates that it is my own record, and - that it is possible
to do better.
