### Bistratic Lace Towers

Lace towers are defined to be stacks of lace prisms, therefore bistratic lace towers are polytopes with exactly 3 vertex layers aligned atop of each other, which all share a common Coxeter symmetry. It shall be pointed out that lace prisms generally allow to consider different edge length symbols. But in this page we restrict to bistratic CRF lace towers, i.e. which have unit edges only and furthermore their 2D faces are considered to be regular. Therefore non-unit edges only can occur as false ones within the medial layer, connecting 2 coplanar lacing faces of the respective segments.

4D

For comparision purposes in the following listings those will be oriented such that the top circumradius is smaller or at most equal to the bottom one. Furthermore, when equal, that the height(1,2) is smaller or equal to the height(2,3). Also, whenever the across symmetry or a reducible part of it has an additional symmetry of its Dynkin symbol, then it will be oriented within lower lexicographic order, except that mere Stott expansion are aligned, i.e. that ooo and xxx are given the same spott, in fact the lexicographical place of the latter one. The same also is used generally for oAo and xBx, when A is any specific edge or pseudo edge length and B = A+x. (For more clarity on the according groupings the first column in each table is added to provide a visually attracting corresponding logical paranthesis.)

In the following lists only axial (external) blends are explicitly mentioned in the remarks columns, as these thus happen to be "mere" axial stacks. None the less, those casually may happen to be special when some of the lacing facets become collinaer / coplanar / corealmic / ... and thus can be considered to be blended in turn. In case this then could be seen in the equatorial dihedral angles column.
