Consider the two types of Grassmannians Gr(2,7) and Gr(3,6) having  their plucker embeddings in $\mathbb P^{20}$ and $\mathbb P^{19}$ respectivley. The first one is 10-dimensional and latter is 9-dimensional, so each having codimension 10. We can easily compute their defining equations and both of them are defined by  35 equations.

By using computer algebra system(such as Macaulay 2 or Magma) we can also compute their Hilbert series and so the Hilbert numerator. If we do the computation then both  varieties have basically same numerator, which suggests that both idels have the same(kind of) free resolution. 

This raises the question whether  Gr(3,6) is a linear section of Gr(2,7) or not.?
