https://en.wikipedia.org/wiki/16-cell%20honeycomb | In four-dimensional Euclidean geometry, the 16-cell honeycomb is one of the three regular space-filling tessellations (or honeycombs), represented by Schläfli symbol {3,3,4,3}, and constructed by a 4-dimensional packing of 16-cell facets, three around every face.
Its dual is the 24-cell honeycomb. Its vertex figure i... |

https://en.wikipedia.org/wiki/Pullback | In mathematics, a pullback is either of two different, but related processes: precomposition and fiber-product. Its dual is a pushforward.
Precomposition
Precomposition with a function probably provides the most elementary notion of pullback: in simple terms, a function of a variable where itself is a function of ... |
https://en.wikipedia.org/wiki/Paley%E2%80%93Zygmund%20inequality | In mathematics, the Paley–Zygmund inequality bounds the
probability that a positive random variable is small, in terms of
its first two moments. The inequality was
proved by Raymond Paley and Antoni Zygmund.
Theorem: If Z ≥ 0 is a random variable with
finite variance, and if , then
Proof: First,
The first addend is... |
https://en.wikipedia.org/wiki/Hall%27s%20universal%20group | In algebra, Hall's universal group is
a countable locally finite group, say U, which is uniquely
characterized by the following properties.
Every finite group G admits a monomorphism to U.
All such monomorphisms are conjugate by inner automorphisms of U.
It was defined by Philip Hall in 1959, and has the universa... |

https://en.wikipedia.org/wiki/Snub%20%28geometry%29 | In geometry, a snub is an operation applied to a polyhedron. The term originates from Kepler's names of two Archimedean solids, for the snub cube () and snub dodecahedron (). In general, snubs have chiral symmetry with two forms: with clockwise or counterclockwise orientation. By Kepler's names, a snub can be seen as a... |
https://en.wikipedia.org/wiki/Carleman%27s%20condition | In mathematics, particularly, in analysis, Carleman's condition gives a sufficient condition for the determinacy of the moment problem. That is, if a measure satisfies Carleman's condition, there is no other measure having the same moments as The condition was discovered by Torsten Carleman in 1922.
