Two-arc-transitive graphs of odd order
WebIn 1971, Tomescu conjectured that every connected graph G on n vertices with chromatic number k ≥ 4 has at most k! (k − 1) n − k proper k-colorings. Recently, Knox and Mohar proved Tomescu's conjecture for WebA. A. Ivanov [4] found a relationship between 2-arc-transitive graphs of girth 5 and flag-transitive geometries with the diagram P L O 0 0 In particular, such a geometry can always be constructed starting from a 2-arc- transitive graph of girth 5 without simple 6-circuits, which is not a pentagraph.

WebDynamic programming is a classical algorithmic paradigm, which often allows the evaluation of a search space of exponential size in polynomial time. Recursive problem decomposition, tabulation of intermediate results for re-use, and Bellman’s Principle of Optimality are its well-understood ingredients. However, algorithms often lack abstraction and are difficult …
Web1 Answer. Let G be the automorphism group and X the set of 3 -arcs of the Petersen graph. We know that G ≥ 120. Because the Petersen graph has girth 5, we can easily count X = 10 ⋅ 3 ⋅ 2 ⋅ 2 = 120. Suppose g ∈ G fixes x = ( x 1, x 2, x 3, x 4) ∈ X. Then g must be the identity: Because the Petersen graph has diameter 2, x 1 ... progressive service phone numberWebMay 9, 2024 · It is shown that each subgroup of odd index in an alternating group of degree at least 10 has all insoluble composition factors to be alternating.

An s-arc in a graph is a vertex sequence (α 0,α 1,…,α s) such that {α i−1,α i} ∈ EΓ for 1 ≤ i ≤ s and α i−1 ≠ α i+1 for 1 ≤ i ≤ s − 1.
