Two out of three.

Yes. Gold star if you include the reasoning.

According to the OP color schemes cannot be repeated. Please use spoilers - PM me if you need help.
-
OP: No two blocks in a set may have the same color pattern. This means that two blocks can't be rotated in such a way they are identical. That is, rotating a block doesn't make a new pattern. Be careful not to overcount.
-
Nope.
-
No. That would be like a 6th color. A careful read of the OP might help here. I think I have the wording right on this puzzle.

No one has it yet. Over and under so far.

Please do a search [for example "ives"] would have turned this up. Locked.

Could the ground floor be given any number, say 13?
-
OK for adding and subtracting floor numbers. What about multiplying and dividing them?

Tony Toynbee the toy maker is busy painting the sides of a set of children's building blocks. The blocks are of traditional cubic shape, and Toynbee has paint of five different colors. No two adjacent sides of a block may have the same color. No two blocks in a set may have the same color pattern. How many blocks are there in the largest set Tony can make?

A man bought 12 lengths of chain, as shown, and asked the local blacksmith to forge them into an endless chain of 100 links. The blacksmith said the cost for splitting and joining small links would be $3 each; for large links it would be $4 each. How much should the man have to pay to have the endless chain made?

Hats on a death row!! One of my favorites puzzles!

Your solution is the correct one. Actually, the solution has been posted more than once. Probably because the thread is so long [ca 300 posts] new solvers don't always read it from the start. -

Guessing gets 50% on average. Your method guarantees 50% Can you guarantee 19? -

To my knowledge the solution is unique [rotation and reflection only].

Of course, it's a different story if we only have to identify the odd ball.

Suppose three intersecting rectangles are drawn in a plane. How can they be arranged to produce the largest number of areas enclosed by their sides, not further subdivided? Example: The figure shows three rectangles A, B and C, that create seven such areas: A B C A B C A B C A B C A B C A B C A B C The area marked 8 is NOT included; not being bounded by the sides of the rectangles.

They're also possibly days of a month. Starting from January, most - but not all - fall on Thursday in 2009.

I agree. Until we've determined whether the odd ball is heavy or light, the number of possible outcomes must be even: that is, 2 times the number of suspect balls. To render 26 outcomes to a manageable level with two weighings to go, the first weighing would have to present three cases of 9, 9, and 8 possible outcomes. One weighing cannot determine the relative weight of the odd ball. So it can't yield a division of cases containing an odd number.
