Automorphisms, flats and erections of pregeometries

2023
We characterize pregeometries in terms of their flats - giving necessary and sufficient conditions for a collection of sets to be the flats of a pregeometry. We begin a systematic study of automorphisms of pregeometries; arguing geometrically, we obtain the (known) factorization of a pregeometry into component pregeometries, and express the ...

A Three-Dimensional Extension to Zatrikean Pregeometry

AIP Conference Proceedings, 2006
The zatrikean abacus was originally defined as a two‐dimensional chessboard‐like lattice with square geobits. In this paper we generalize the zatrikean abacus in three dimensions by using a three‐dimensional lattice with cubic geobits. We then calculate the values of certain interesting pregeometric quantities for the solar system.
