Cameron–Fon-Der-Flaass IBIS theorem
In mathematics, Cameron–Fon-Der-Flaass IBIS theorem arises in the dynamical algebraic combinatorics. The theorem was discovered in 1995 by two mathematicians Peter Cameron and Dima Fon-Der-Flaas.[1] The theorem is considered to be a link between group theory and graph theory as it studies redundancy of a group.[2][1]
Statement
Let be a permutational group of ,[clarification needed] then the following are equivalent:
- Irredundant bases of are stored by re-ordering.
- The bases of matroid are formed due to the irredundant bases of .
- Every irredundant base of got the same size.
