Dr. Pepper-
Neat solution – basically you’re removing a diagonal strip the width of one cube’s diagonal from the lower left corner to the upper right corner of a 15 cube x 15 cube square.
I have no idea how you even come up with this (and this is probably an easier problem for math meivinim).
Do you want to publish a paper on this with me? You can earn an Erd?s number of 5.
Well, thanks to Google I now know what an Erd?s number is.
As far as your offer, usually an Aleph Bina is not published in the same volume as a sefer Kabala ?.
