NUMBER OF RESTRICTION MAPS:   2                         TOTAL RELS:   10

Total relations: 10.
Total independent relations: 9.
Because the net set of coefficients has size 10, this implies S₄¹⁰ has dimension at most 10-9=1. Since S₄¹⁰ contains G₁₀, we conclude dim S₄¹⁰ = 1.

ell: This is the level.
The next 10 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.
