Let $A=k[x,y,z]$ for a finite field $k$ and let $J=<x,y,z,>$ be="" the="" ideal="" generated="" by="" x,y="" and="" z.="" call="" an="" ideal="" $i$="" of="" $a$="" $r$-admissible="" in="" case="" $j^r="" \subseteq="" i="" \subseteq="" j^2$.="" can="" sage="" find="" all="" 4-admissible="" ideals="" for="" a="" given="" finite="" field="" (lets="" say="" with="" 2,3="" or="" 5="" elements="" for="" a="" start)?="" this="" is="" one="" of="" the="" easiest="" special="" cases="" of="" a="" more="" general="" problem,="" which="" is="" probably="" too="" hard="" and="" too="" slow="" for="" todays="" computer.="" but="" maybe="" sage="" can="" do="" it="" in="" principle?<="" p="">
