This document is a draft of charted instructions for knitting a cabled entrelac cube with 24 squares. I haven't knitted from these charts, so there may be some errors. I'm providing this for anybody who would like to attempt the knitting. I will help if you get stuck... hopefully by the time you get to the sticking point I will have already knitted past you.
ETA: I found an error in the chart, the symbol for Purl 2 together (on right-side rows) is actually only used on wrong-side rows. Oops.
