Abstract: Abstract We are interested in the structure of almost complete intersection ideals of grade 3. We give three constructions of these ideals and their free resolutions: one from the commutative algebra point of view, an equivariant construction giving a nice canonical form, and finally an interpretation in terms of open sets in certain Schubert varieties.
