nce of a solution, but the divisors in the congruence equations for the superior epoch are not pairwise coprime. This means that the equations may not have a solution unless the remainders in the equations satisfy certain conditions, but the Chinese remainder theorem doesn't provide any method to check the existence of a solution. In the case of no solution, there doesn't seem to have an easy way to fix the situation. Another, unrelated, puzzle is that if the number of years from the superior epoch N was co
