Direct constructions for certain types of HMOLS

R.Julian R. Abel, Hantao Zhang
1998 Discrete Mathematics  
In this paper, we present 16 new types of three holey mutually orthogonal Latin squares (3-HMOLS for short) with equal-sized holes, along with 7 sets of 4-HMOLS, 2 sets of 6-HMOLS, and 34 sets of 7-HMOLS  ...  We also provide some new sets of HMOLS that have n holes of size 2 and one hole of size 3.  ...  Vincent University when part of this resarch was done and wishes to thank their Department of Mathematics for the services provided.  ...

A lower bound on HMOLS with equal sized holes [article]

Michael Bailey, Coen del valle, Peter J. Dukes
2020 arXiv   pre-print
We generalize a difference matrix method that had been used previously for explicit constructions of HMOLS. An estimate of R.M.  ...  For h≥ 2, relatively little is known about the quantity N(h^n), which denotes the maximum number of 'HMOLS' or mutually orthogonal latin squares having a common equipartition into n holes of a fixed size  ...  The outline of the rest of the paper is as follows. In Section 2, we obtain a direct construction of k HMOLS of type h q for large prime powers q.  ...

Complexity of Molecular Nets: Topological Approach and Descriptive Statistics

Alexander M. Banaru, Sergey M. Aksenov
2022 Symmetry  
The contribution of Hmol into HmolNet ranges from 35 to 95% (mean 79%, SD 6%), and the subset of bearing intermolecular contacts accounts for 41 to 100% (mean 62%, SD 11%) of the complexity of the full  ...  The normalized value of HmolNet is of the logistic distribution type and is distributed near 0.85HmolNet with a small standard deviation.  ...  Any graph with certain types of vertices may be considered as a message, as well.  ...

On the Spectra of Certain Classes of Room Frames

Jeffrey H. Dinitz, Douglas R. Stinson, L. Zhu
1994 Electronic Journal of Combinatorics  
In this paper we study the spectra of certain classes of Room frames. The three spectra are incomplete Room squares, uniform Room frames and Room frames of type $2^ut^1$.  ...  These problems have been studied in numerous papers over the years; in this paper, we complete the three spectra except for one possible exception in each case.  ...  Acknowledgements Part of this research was done while the second author was visiting the University of Nebraska-Lincoln in March 1994, with support from the Center for Communication and Information Science  ...
