Let's start out with a combination of Pyramid 4 and Dial 1.
An AU swap takes place as in Dial 4. The letter A is swapped with the letter O and the U is swapped with the letter V.
The deciphering mechanism dictates that the S edge perform a prev/next replacement first. By applying the rules in Pyramid 8 the letter D is replaced with the letter R and the letter M is replaced with the letter T.
The deciphering mechanism dictates that the D edge perform a prev/next replacement second. By applying the rules in Pyramid 8 the letter S is replaced with the letter C.
Overlaying the all red pyramid with the original blue pyramid displays how the letters DOUOSVAVVM map into TUUOUCAVAR.
