Perfect hexagon triple systems
Discrete Mathematics, 2004 This paper gives necessary and sufficient conditions (with only two exceptional cases which remain open) for the existence of perfect maximum packings of \(3kK_n\) with hexagon triples. Here a hexagon triple is a collection of three triples \(abc\), \(cde\), \(efa\) forming a hexagon.

BACK TO BASICS: TOWARDS NOVEL COMPUTATION AND ARRANGEMENT OF SPATIAL SENSORY IN IMAGES
Acta Polytechnica, 2016 The current camera has made a huge progress in the sensor resolution and the lowluminance performance. However, we are still far from having an optimal camera as powerful as our eye is.

Hexagonal systems with fixed bonds
Discrete Applied Mathematics, 1993 Skeletons of benzenoid hydrocarbon molecules are presented by hexagonal systems \(H\), i.e. 2-connected subgraphs of the hexagonal grid graph. An edge of \(H\) is called a fixed bond if it is contained in all or in no perfect matching of \(H\). An \(O(n^ 2)\) algorithm to determine fixed bonds in a hexagonal system is given.

Discrete Mathematics, 2008 AbstractA hexagon quadrangle system of order n and index ρ [HQSρ(n)] is a pair (X,H), where X is a finite set of n vertices and H is a collection of edge disjoint hexagon quadrangles (called blocks) which partitions the edge set of ρKn, with vertex set X.

The fundamental group and Galois coverings of hexagonal systems in 3-space
International Journal of Mathematics and Mathematical Sciences, 2006 We consider hexagonal systems embedded into the 3-dimensional space ℝ3. We define the fundamental group π1(G) of such a system G and show that in case G is a finite hexagonal system with boundary, then π1(G) is a (non-Abelian) free group.
