Residue Theorem (Group)
If two groups are residual to a third, every group residual to one is residual to the other. The Gambier extension ofthis theorem states that if two groups are pseudoresidual to a third, then every group pseudoresidual to the first withan excess greater than or equal to the excess of the first minus the excess of the second is pseudoresidual to the second, with anexcess
