So far I've only done a few easy ones.

**Spoiler:**

Simple substitution cipher, but with stick figures, a la The Adventure of the Dancing Men. The plaintext is "started with four letters but only need three what a riddle what a mystery." I'm not certain what it means.

**Spoiler:**

Assuming z is at least 2, [math]\int_0^\infty t^{z-1} e^{-t} dt=\left [-t^{z-1}e^{-t} \right ]_0^\infty+\int_0^\infty t^{z-2} e^{-t} dt=\int_0^\infty t^{z-2} e^{-t} dt.[/math]

So by induction, this is equal to [imath]\int_0^\infty e^{-t} dt=[-e^{-t}]_0^\infty=1[/imath] for any whole number z. I'm not quite sure what 1ing is, so I may have made a dumb mistake...

**Spoiler:**

The start of the tenth-favorite word used by Bender: C (for Chump)

The toon that went south while commanded by Ender: B (first battle, against Rabbit)

The number of lights that Picard said were on: 4 (Chain of Command)

And the class of the planet where Kirk shouted "Khaaan!":

I'm not sure about this one - it's been a while since I watched Wrath of Khan. A friend of mine, who's a bigger trak geek than I am, says this took place on Ceti Alpha V, which Memory Alpha lists as "barely class M" prior to the events of WoK, but was class H during WoK. However, the WoK article seems to imply that the enraged shout took place not on the planet but on an asteroid. My guess is H, but confirmation would be nice

The rings of the men minus rings for the elves: 9-3=6

And the product mod ten of a foursome of twelves: 12

The end of a code NES gamers know: assuming you don't count select+start, A

And the base used to model how quickly things grow: e

When xor'd together, we're supposed to get 'E', but this doesn't seem to be the case (unless the planet was T class, which seems unlikely), so there must be some mistake here.

Also, I'm not quite sure what's up with the page numbers. As far as I can tell

**Spoiler:**

They are all sequences of 0s, 1s, and 2s, in length-lexicographic order (which is the same as increasing order of the number they represent in base 3, or any base >3 such as 10) such that a '2' can only be followed by '0's. I can't come up with a nicer description, or any reason why this would be interesting.
