Impartial avoidance and achievement games for generating symmetric and alternating groups
We study two impartial games introduced by Anderson and Harary. Both games
are played by two players who alternately select previously-unselected elements
of a finite group. The first player who builds a generating set from the
jointly-selected elements wins the first game. The first player who cannot
select an element without building a generating set loses the second game. We
determine the nim-numbers, and therefore the outcomes, of these games for
symmetric and alternating groups.Comment: 12 pages. 2 tables/figures. This work was conducted during the third

A central partition of molecular conformational space. II. Embedding 3D structures
A combinatorial model of molecular conformational space that was previously
developped (J. Gabarro-Arpa, Comp. Biol. and Chem. 27, (2003) 153-159), had the
drawback that structures could not be properly embedded beacause it lacked
explicit rotational symmetry. The problem can be circumvented by sorting the
elementary 3D components of a molecular system into a finite set of classes
that can be separately embedded. This also opens up the possibility of encoding
the dynamical states into a graph structure
Jonzac – Le Moulin de Chez Bret
Identifiant de l'opération archéologique : 204305 Date de l'opération : 2008 (FP) Inventeur(s) : Robin Karine (COL) La fouille programmée menée à proximité du Moulin de chez Bret à Jonzac a mis au jour une première occupation de la seconde moitié du Ier  s. avant J.-C. Une villa est ensuite construite à partir du milieu du Ier  s. apr. J.-C. Elle est occupée jusqu’à la fin de l’Antiquité tardive voir le début du Haut Moyen-Âge. Les structures les plus précoces correspondent à un fossé asso..
Holotype of Agathymus escalantei Stallings, Turner, and Stallings, 1966 (Lepidoptera: Hesperiidae: Megathyminae)
Agathymus escalantei Stallings, Turner, and Stallings, 1966 (Lepidoptera: Hesperiidae) is the only described species of Megathyminae known from a single collected individual. To date, the only images of this specimen are poor black and white illustrations published in the original description. This note presents the first color photographs of the holotype
