The circuit rank of a graph G may be described using matroid theory as the corank of the graphic matroid of G. [4] Using the greedy property of matroids, this means that one can find a minimum set of edges that breaks all cycles using a greedy algorithm that at each step chooses an edge that belongs to at least one cycle of the remaining graph.
The length of a cycle is the number of elements of its largest orbit. A cycle of length k is also called a k-cycle. The orbit of a 1-cycle is called a fixed point of the permutation, but as a permutation every 1-cycle is the identity permutation. [7] When cycle notation is used, the 1-cycles are often omitted when no confusion will result. [8]
A cyclic number is an integer for which cyclic permutations of the digits are successive integer multiples of the number. The most widely known is the six-digit number 142857, whose first six integer multiples are 142857 × 1 = 142857 142857 × 2 = 285714 142857 × 3 = 428571 142857 × 4 = 571428 142857 × 5 = 714285 142857 × 6 = 857142
n − 5 fixed points, a three-cycle and a two-cycle, or; n − 4 fixed points and a four-cycle. The three types may be enumerated as follows: choose the six elements that go into the two-cycles, decompose them into two-cycles and take into account that the order of the cycles is not important:
Formula 4 is the first step out of karting on the FIA Global Pathway, and by design has the least performance of any of the cars in it. Compared to road-legal supercars, Formula 4 cars are less accelerative and have a much lower top speed of approximately 240 km/h; most modern supercars are capable of in excess of 300 km/h. The F4 cars have far ...

A cubic graph (all vertices have degree three) of girth g that is as small as possible is known as a g-cage (or as a (3,g)-cage).The Petersen graph is the unique 5-cage (it is the smallest cubic graph of girth 5), the Heawood graph is the unique 6-cage, the McGee graph is the unique 7-cage and the Tutte eight cage is the unique 8-cage.
