algebraicMatroidCircuits -- The bases of the algebraic matroid

Usage:

C = algebraicMatroidCircuits L
Inputs:
- L, an instance of the type GrMatchingField,
Outputs:
- C, a list, the circuits of the algebraic matroid of the matching field as $k$-subsets

Description

Displays the circuits of the algebraic matroid associated to the Grassmannian Gr$(k,n)$ matching field in terms of the $k$-subsets of $[n]$. For more details about the matroid, see the function algebraicMatroid.
