To better see how the components described fit in to the complete cipher, this diagram, showing part of the third round, and the fourth round, of the basic cipher, and the first of four rounds of the first group of four core rounds, in a more schematic form and on a smaller scale is provided:
Even as an overview of a small portion of the cipher, the diagram is quite large, occupying 1280 by 1024 pixels.
Also, remember, unlike the rounds shown within, the cryptographic core rounds are not performed in place; instead, the 64-bit halves of the 128-bit block are swapped after each of the first three of each group of four cryptographic core rounds.
