... There are two main thrusts in the theory of regular and chiral p olytop es: the abstract, purely combinatorial asp ect, and the geometric one of realizations. ... The dimension of a faithful realization of a finite abstract regular p olytop e in some euclidean space is no smaller than its rank, while that of a chiral p olytop e must strictly exceed the rank. ... In E4 , therefore, the open cases are the (finite) chiral polytopes of rank 3, and the regular or chiral apeirotopes of ranks 3 and 4. ...
