How would you describe the following pattern?:
For each primorial from 30 onward, there exists a pattern in the arrangement of the prime factors of the composite numbers which I call "the mirror patterns". For each of these mirror patterns, there is a set of five whole numbers to which I have assigned the names $Zero$, $the$ $Left$ $Mirror$ $Center$, $the$ $Central$ $Number$, $the$ $Right$ $Mirror$ $Center$, and $the$ $Product$. Here is the set of these five whole numbers for the primorial 30: $$0,4,15,26,30$$ Surrounding 4 are the prime numbers 3 and 5.
Surrounding 26 are the prime factors 5 and 3.
$$15=3·5$$
