Abstract
A symmetry extension of Maxwell's rule for rigidity of frames is found. Thi s rule subsumes and strengthens Maxwell's 1864 rule by requiring that the i nternal and external degrees of freedom of a pin-jointed structure are not only numerically equal, but are also equisymmetric, A number of special cas es of Maxwell's original rule are studied to show the improved insight that the symmetry-adapted version can give.
