Rules for Folding Polyminoes from One Level to Two Levels
Julia Martin, Elizabeth Wilcox
Polyominoes have been the focus of many recreational and research investigations. In this article, the authors investigate whether a paper cutout of a polyomino can be folded to pr…
Quasi-Antichain Chermak-Delgado Lattices of Finite Groups
Ben Brewster, Peter Hauck, Elizabeth Wilcox
The Chermak-Delgado lattice of a finite group is a dual, modular sublattice of the subgroup lattice of the group. This paper considers groups with a quasi-antichain interval in the…
Chermak-Delgado Lattice Extension Theorems
Lijian An, Joseph Brennan, Haipeng Qu +1
In a finite group G with subgroup H, the Chermak-Delgado measure of H (in G) is defined as the product of the order of H with the order of the centralizer of H. The Chermak-Delgado…
Groups Whose Chermak-Delgado Lattice is a Chain
Ben Brewster, Peter Hauck, Elizabeth Wilcox
For a finite group G with subgroup H the Chermak-Delgado measure of H in G refer to the product of the order of H with the order of its centralizer, C_G(H). The set of all subgroup…
Some Groups with Computable Chermak-Delgado Lattices
Ben Brewster, Elizabeth Wilcox
Let G be a finite group and let H be a subgroup of G. The Chermak-Delgado measure of H with respect to G is the product of the order of H with the order of the centralizer of H. Or…
