NUMBER OF RESTRICTION MAPS:   1                         TOTAL RELS:    1

Total relations: 1.
Because the net set of coefficients has size 2, this implies S₄⁸ has dimension at most 2-1=1. Since S₄⁸ contains J₈ (Schottky form), we conclude dim S₄⁸ = 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 M₁³²(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.
