✦ Synopsis

An integer matrix whose determinant computes the cuspidal class number of the modular curve X 1 (m) is obtained. When m is an odd prime, this will provide us with an upper bound of the class number.

## Abstract It has been long conjectured that the crossing number of __C~m~__ × __C~n~__ is (__m__−2)__n__, for all __m__, __n__ such that __n__ ≥ __m__ ≥ 3. In this paper, it is shown that if __n__ ≥ __m__(__m__ + 1) and __m__ ≥ 3, then this conjecture holds. That is, the crossing number of __
