Corrected entry: When Kate walks over to the silver frame and says "It's Jerry's diagram," all the numbers which were previously written, appear on the frame. However the "9", which should be on the bottom of the frame behind her, is missing. (01:17:35)

Correction: We know that there are alternate dimensions in the Hypercube, so that particular diagram could very well have been made by a different Jerry than the one that the movie follows.
