Specifically, it is derived from the first homology group of the knot complement, which can be computed using a Seifert surface.

The problem asks whether it is possible to find a connected graph on 99 vertices in which every vertex has an even degree. In graph theory, a fundamental result is that a graph can only be Eulerian (i.e., it contains an Eulerian circuit that visits every edge exactly once) if every vertex has an even degree.

The notation "II25,1" is not immediately recognizable as it does not correspond to a commonly known concept or term in popular subjects like mathematics, science, literature, or coding. However, if we break it down: - "II" could stand for the Roman numeral for 2, or it might denote a set of items, categories, or sections.
Icosian refers to a type of mathematical problem or puzzle related to a specific graph known as the icosahedron. The term is often associated with the Icosian game, which involves finding a Hamiltonian cycle in the graph representing the vertices and edges of an icosahedron.

Start with an initial term, usually "1".
