Self-complementary magic squares.
Ars Comb., 2014This paper considers magic squares on the symbols 1 to \(n^2\). The complement of such a square is obtained by replacing each symbol \(s\) by \(n^2+1-s\). Two magic squares are equivalent if one can be mapped to the other by some element of the dihedral group of order 8. A magic square is self-complementary if it is equivalent to its complement.

On strongly regular self ‐ complementary graphs
Journal of Graph Theory, 1981AbstractIt is shown that certain conditions assumed on a regular self‐complementary graph are not sufficient for the graph to be strongly regular, answering in the negative a question posed by Kotzig in [1].

Self-complementary circulant graphs
Ars Comb., 1999Summary: There exists a self-complementary circulant graph with \(n\) vertices if and only if every prime \(p\) in the prime factorization of \(n\) satisfies \(p \equiv 1\) (mod 4).

Chemistry (Weinheim an der Bergstrasse, Germany)
Three [3]catenanes with cavities large enough to accommodate aromatic guests have been designed and synthesized (yields = 5-20 %) by means of kinetically controlled self-assembly processes. The X-ray structural analysis of one of three [3]catenanes confirmed the presence of a rectangular cavity (dimensions = 7 x 11 A) lined by pi-electron-rich ...

The paper is mainly concerned with the class K of finite groups defined as follows: \(\Gamma\in K\) if \(\Gamma\) has an automorphism \(\sigma\) and a subset H such that \(\Gamma \setminus \{e\}=H\cup H^{\sigma}\), \(H\cap H^{\sigma}=\emptyset\) and \(h\in H\Rightarrow h^{-1}\in H\).
