Is this a "two-step ladder radar" since each digit varies by 2?

Except for the minor detail that 9 is not prime. ;) Now if you were talking about 1357531, or 7531357, that would be a prime digit two-step ladder radar. (What a name!)

It is an X note of course. Woops, after the <x (subscript 5), there is supposed to be "<x (subscript 6)"

Or if it were 1235321 it would be an ascending/descending Fibonacci sequence ladder note.   8-)

9753579 to me is a descending/ascending ladder note with half its rungs missing.  :)

Ahh!... but wouldn't a Fibonacci radar be:
1123211?  

Woops, actually, according to Wiki (see image), it should be:
0112110
Hey I just learned something!  

AND! (for us math geeks), there are only FIVE possible fibonacci serial numbers in our current 7 digit notes.
f-31 : 1346269 = 557 x 2417 (the factors)
f-32 : 2178309 = 3 x 7 x 47 x 2207
f-33 : 3524578 = 2 x 89 x 19801
f-34 : 5702887 = 1597 x 3571
f-35 : 9227465 = 5 x 13 x 141961

Okay, now I have yet another wacky set to try to put together!

I always believed in KISS (keep it short/simple)

That's why I'd like to bid $1 billion dollars 8-)on this:

semi-prime descending-ascending two-step escalator radar note with quasi-fibonacci sequences :o

I could show it off at next year's CNS (charge five bucks per view) and regenerate a few circulated radars with the proceeds.

That is nuts!  I think that would be a set of seven symbols for "empty set" :) You know, the "zero" with the slash through it.
