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

I would just call it a normal 4 digit radar  thats just me  Arthur

Jazz it up a little    How about a "prime" digit radar?

Jazz it up a little    How about a "prime" digit radar?

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!)

how about an odd numbered ladder

You can call it a missing steps ladder note.  

I Like...

2-Step Ascending/Descending almost Prime Digit Laddering 4-Digit Radar Note

 

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

HAHAA!!  Man I love threads like these! 8-)

E = mc²

2-Step Ascending/Descending almost Prime Digit Laddering 4-Digit almost ROTATOR-Greek like near Solid Digit end of Prefix Radar Note  

Now if you were talking about 1357531, or 7531357, that would be a prime digit two-step ladder radar. (What a name!)

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.  

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

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

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.

Believe me, I have my fair share of weird sets. Currently trying to get a note that resembles the numeric pattern of the Royal Sampler. (But would have to do this on US currency) 

Q: What cards does Homer have when he's told he has the Royal Sampler?
A: When Homer and the Stonecutters are playing poker in Homer The Great, Homer's "Royal Sampler" consists of a three, six, ten, jack, and king.

I think that that would be a (from left to right):
3 6 10 11 13

With enough interest being shown in these special numbers, maybe the Charlton catalog will eventually have a premium for just the general category of a special number , eg Pi 3141592 or e 2718281 (truncated decimal places of course).  As a collector, I would pay a premium for notes such as these. However, I may be one of a few as they may only appeal to the mathematically inclined although I would think they have a greater appeal than birthyear notes which have their own designation in Charlton's.

My greatest fear is that people who attend Star Trek conventions will start collecting paper money  

...first "Trekkies" and then "DaVinci Code" addicts to follow.  That would encourage all those who collect low grade sticky notes to market them as "Klingon" notes.  I'd hate to hear that the queen is really Leonardo Da Vinci in drag!

But seriously folks:  not all radars have the same appeal.  Isn't it common for us to see 3 digit radars such as 0028200 go for a bit of a premium over say 2028202?  (I know I'd take the first # over the second#)

And what about simple two digit notes?  I sold a D/E 0011011 devils face for about $20 over book to a dealer.  I know I love two digit notes and will pay premium for them (though there's no mention of this in Charlton).  Though in all fairness to Charlton-- it really has improved drastically with the addition of change-overs and other errors.  It truly is catching up.

As the author of the post referenced in the link below, I think I can say with some authority that walktothewater was mildly to moderately under the influence of ____ (??) when he wrote his post above.

walktothewater, I'll have to show you my hyper-planchetted note some time...

Not talking for fabonacci number or other.
I have one US note (per scan image).  Is that call a even number ladder ascending / descending notes?
Thank you.
