Abstract:

In this paper we define an interesting family of perfect ideals of codimension three, with five generators, of Cohen-Macaulay type two with trivial multiplication on the $\operatorname {Tor}$ algebra. This family is likely to play a key role in classifying perfect ideals with five generators of type two.
