isElementaryQuotient(M, N)
This function is provided by the package Matroids.
An elementary quotient of a matroid N is a quotient M whose rank is the rank of N minus one. Elementary quotients are completely determined by the modular cut of flats in M (which are also flats of N) whose rank in M is one less than their rank in N. Examples of elementary quotients of N are its principal truncations with respect to a given flat F.






The object isElementaryQuotient is a method function.
