I’m not entirely sure what this is. Only that it has been stuck in my head for close to 15 years now. The pattern in the higher primes and their multiples is probably known and I have probably gone through a strange and roundabout way to find a generally useless but curious anomaly. But, I just needed to get this out there and see what people think drop me a line and let me know. This will probably grow. 
The 1 and the 7 are the stick and the angle respectively. The 4 combines the stick and the angle the 1 and 7 are prime, the 4 is not. 
The 2 hooks the top, crossing the bottom and the 5 hooks the bottom, crossing the top. The 8 encircles both the 2 and 5 are prime, the 8 is not. 
The 6 circles the bottom and hooks the top and the 9 circles the top and hooks the bottom. The 3 hooks the top and bottom 3 is prime, while 6 and 9 are not. 

In numerology, the “root” of a number is found by adding all of it’s digits, if this results in a number with more than one digit, these are then added until you get a single digit this is the numerological root. Here you can see the 147, 258 and 369 sequence continues on infinitely, it makes sense, there’s no reason for it not to.



When we start looking at the patterns of multiplication, it gets kind of interesting the 2 times table is a nice checker board.
The 3 times table is the whole last column and, of course, it also contains the 6s and 9s the 6s are all the even ones and the 9s are the ones whose “root” is 9. Red – multiple of 6 (even) Yellow – multiple of 9 (root 9) Orange – multiple of 6 and 9 (even, root 9)


Here we have the 5 times table. Note that as it bounces through each column, it hits on each root cyclically,albeit in a different order: 174, 528 and 639.
The 5 times table is fun because you can do it in your head the “root 9” at the end of the table is from 45 from there it goes 5 (50), 1 (55), 6 (60), 2 (65), 7 (70), 3 (75), 8 (80), 4 (85) and back to 9 (90). If you look back to the 2s, you will see that it does the same thing (just with a different starting point); 417, 285 and 639. 

Higher Primes and Their Multiples
This is when I dug a little deeper (or perhaps went off the rails), when I coloured all the multiples of the lower numbers and found a pattern in the “holes”. In the table, the + numbers at the top of each column is what was added to the previous number to get the number shown. So, starting from 1 (not shown), we +6 to get 7, +4 to get 11, +2 to get 13 and so on. 

Looking at each of the columns, I noticed 2 striking things:
The other thing to note about this overall set is that it contains only primes and multiples of other numbers in the set. After eliminating 49, 77, 91, 119, 133, 161, 121, 143, 169 from the above table, all the remaining numbers are prime. Or maybe not, but this is the idea that’s been buzzing around my brain and needed to get out, hope it stirs some brain cells.
