In 7-dimensional geometry, there are 127 uniform polytopes with E7 symmetry. The three simplest forms are the 321, 231, and 132 polytopes, composed of 56, 126, and 576 vertices respectively. They can be visualized as symmetric orthographic projections in Coxeter planes of the E7 Coxeter group, and other subgroups. (Wikipedia).

The Art of Traditional Japanese Wood Joinery 日本伝統の技術『仕口・継手』
At the end of the 12th century, fine woodworking skills and knowledge were brought into Japan from China. Over time, these joinery skills were refined and passed down, resulting in the fine wood joineries Japan is known for. Here are some examples of traditional wood joineries which are s

Giuseppe Mussardo - 2D Ising Model and its tricritical version, when theory meets experiments
The magnetic deformation of the 2D Ising Model and the thermal deformation of the Tricritical Ising Model are related to the exceptional E_8 and E_7 Lie algebras. The corresponding exact S-matrix theories and the related dynamical structure factors of both models have a rich spectroscopy

Stephan Weltge: Binary scalar products
We settle a conjecture by Bohn, Faenza, Fiorini, Fisikopoulos, Macchia, and Pashkovich (2015) concerning 2-level polytopes. Such polytopes have the property that for every facet-defining hyperplane H there is a parallel hyperplane H0 such that H and H0 contain all vertices. The authors con

Raman Sanyal: Polyhedral geometry of pivot rules
Geometrically, a linear program gives rise to a polyhedron together with an orientation of its graph. A simplex method selects a path from any given vertex to the sink and thus determines an arborescence. The centerpiece of any simplex method is the pivot rule that selects the outgoing edg

Steffen Borgwardt: The role of partition polytopes in data analysis
The field of optimization, and polyhedral theory in particular, provides a powerful point of view on common tasks in data analysis. In this talk, we highlight the role of the so-called partition polytopes and their studies in clustering and classification. The geometric properties of parti
