The length of the first column gives the cardinality.
columns belong to potentially infinite collections.
actually infinite, i.e., has length |ℕ|.
There are infinitely many rows with infinitely many numbers. Nevertheless all rows are of length smaller than |ℕ| and therefore by symmetry also the first column is of length smaller than |ℕ|.
