NUMBER OF RESTRICTION MAPS:   1                         TOTAL RELS:    8

Total relations: 8.
Because the net set of coefficients has size 8, and these 8 relations are independent, this implies S₅⁸ has dimension at most 8-8=0. That is, dim S₅⁸ = 0.

ell: This is the level.
The next 15 numbers give the entries of the matrix.
The cusps (of G₀(ell)) are listed vertically in form a/c. To the right of each of these is the maximum term kept in the corresponding cusp expansion. For example, q^15/3 would indicate that the expansion is in powers of q^1/3, and that we keep the first 16 terms (q^0/3 through q^15/3).
The number under "terms" is the total number of terms kept over the various cusps.
The next entry is dim M₁⁴⁰(G₀(ell)).
The number under "rels" is the number of relations (on the net set) obtained from this particular restriction map. The number is usually the difference between the "terms" and "dim" unless the matrix has some "self-similarity" in the sense that the matrix box-operation with a cusp yields something that is a multiple of the original matrix.
