The Coxeter – Todd lattice , the Mitchell group , and related sphere packings
This paper studies the Coxeter-Todd lattice Ag, its automorphism group (which is Mitchell's reflection group 6-P$C7(4,3)-2), and the associated 12-dimensional real lattice K12. We give several constructions for Ag, which is a Z[w]-lattice where w = e ; enumerate the congruence classes of Ag/2Ag and A%/6A%, where 6 = to — <D; prove the lattice is unique; determine its covering radius and deep ho...
متن کاملLow dimensional strongly perfect lattices . I : The 12 - dimensional case
It is shown that the Coxeter-Todd lattice is the unique strongly perfect lattice in dimension 12.
متن کاملThe ternary Golay code, the integers mod 9, and the Coxeter-Todd lattice
The 12-dimensional Coxeter-Todd lattice can be obtained by lifting the ternary Golay code to a code over the integers mod 9 and applying Construction A. Several recent papers have pointed out connections between codes over & and lattices [l], [3]. It is the a m of this correspondence to show that the Coxeter-Todd lattice K12 ([4], [5, ch. 4, sec. 91) can be obtained in a similar way from a code...
متن کاملRigidity of spherical codes
A packing of spherical caps on the surface of a sphere (that is, a spherical code) is called rigid or jammed if it is isolated within the space of packings. In other words, aside from applying a global isometry, the packing cannot be deformed. In this paper, we systematically study the rigidity of spherical codes, particularly kissing configurations. One surprise is that the kissing configurati...
متن کاملLife history variation in the gastropod genus Lavigeria (Thiaridae) of Lake Tanganyika Note: this text is an English translation of the paper
For example among the gastropods 80% of the species found in the lake are endemic. Most diversity is displayed in the family Thiaridae. The genus Lavigeria it is the most common thiarid genus and at the same time the most diverse (Michel 1995). It has an estimated species diversity of 20 or more endemic species (Michel & Todd, in prep). The often sympatric species show many shell morphological ...
