Rotatable RADAR vs. SWIMS

News: Registration is free here at the CPMF!

I stopped by Vern's booth at Torex and he showed me a "rotatable radar"...  I don't remember the number but an example would be 6080806 which is 9080809 when rotated. This note is a radar and is also a radar when rotated but is not a rotator.
Now 6080809 is not a radar but is a rotator.

Rotatable radars would thus be any radar where the serial number contains only 0, 6, 8, or 9.

Can we think of another name which would be less confusing between rotatable radar and rotator?

Oh boy... Now this will really muddy the waters. Some people can't quite wrap their head around the rotators idea. Do we really want to get into this? We'd have to classify #s like 6698008 too. Let's not. Leave them as radars and rotators.

Brent just did the math... there are 128 rotator notes and 128 rotatable radars in each prefix of 10,000,000 notes.

You guys have got me all confused.  

Now what do I call this one?

rotatable radar,
radar when rotated,
rotator,
or radar.

Solid.

I like SWIMS.

Because, if you invert the word SWIMS, you still get SWIMS. Just like a rotator, or should I say rotator radar, or...

I like SWIMS.

8888888  I'd call that a TRANSILLUMINATABLE ROTATABLE RADAR because if you shine a very bright light through the note and look at the other side it is still a solid radar, right side up and up side down.

Do they even HAVE doctors that can help you?

This is one more reason why I love this site.  You guys are great.  
All the suggestions are good ones, but "Solid Radar" is good enough for me.

eyevet and I get along just swell, don't we, doc? We poke fun at each other and annoy ourselves routinely, but everything is in good fun. We're also the source of several running jokes here at the forums, including the Mackie/Merritt signature set that is soon to be released!

Shouldn't a Rotatable Radar only contain 8's or 0's if you have a number like 9000006, it is not a radar, but is rotatable.  Numbers like 9000009 should just be radars?

You are correct.

This is the crux of what is confusing:  

9000006  is not a radar it is a SWIMS or "rotator" as when it is inverted the number still reads 9000006.

9000009 is a radar, but it is not a rotator as when inverted it reads 6000006 which is a different number.  But it is a rotatable radar since the number is a radar when read right side up or upside down - not the same number but still a radar.

Transilluminatable radars can only have 0's and 8's as these are the only two numbers that can be rotated around its verticle axis and still be the same number.

Oh will you please be quiet!? You're complicating the matter immensely, not just because you're introducing another weird classification, but also because you're using such a horrific word that takes some concentration even to pronounce! It's a rotator, or a radar, or a solid. Jeez.

Then what is a note numbered 8000008 called? What about 8000000? I own a consecutive run of Bird $50s with numbers 8000000-8000009.
