Q: Perambulating ants 2

postmortesThe ants from this puzzle have been placed into a new arena: a cross-shaped hallway with a pillar (black square) in the centre and four statues (numbered 1-4) set symmetrically. The ants, like last time, start off by trying to move East. If they encounter a boundary, the central pillar, a stat...

starting to think that "song from the king" as the def is a dead end
went through wikipedia's list of songs recorded by elvis... only six have 8 letters and none fit the hint given in the other room
("Britches", "Clambake", "Crawfish", "Memories", "Snowbird" and "Speedway")
11:14 AM
Yeah, I did the same research. :-)
And then I Googled for songs sung by Jesus, and apparently Mark and Matthew say he sang but don't say what he sang, and some Web page suggests certain psalms he would've sung, but that seems too far a stretch and anyway I don't know what word it would clue.
11:32 AM
I've followed the same dead end and I've now looked at the hint in OK's home.
there's of course BB king but i'm not sure if he's commonly called "the" king
THRENODE is another spelling of threnody, which is a song of lament that has a king (R = rex) in THE and then NODE, a reversal of EDO castle and N (endless (du)N(es))? If so, I think the reversal is a bit off.
surely endless doesn't mean "just the middle"? i think it's supposed to be either remove last letter or both the first and last
Yes, that's taking away too much. It's a stretch, I know.
The only useful synonym for dunes I can think of is "sand".
12:07 PM
@MOehm I dunno what you mean by "off". "About" can mean "reversed" (as in "about face"), but then the components are out of order: should be "endless dunes castle about", if you will. (Plus, as already mentioned, it uses "endless" for grabbing the middle letter of a five-letter word.)
@MOehm hills, desert, and their synonyms...
12:19 PM
I mean that if it is really NODE = (EDO + N)<, then the reversal indicator "about" is in the middle, which doesn't feel quite right. And I find those synonyms very loose, especially since the dunes don't have any relation to the rest of the surface.
But as I said, It's a stretch. I do like the "King in the" part, though.
(Perhaps I ike it so much that I try to make rest of the solution fit, no matter what.)

Q: Replace "?" in a squence of numbers

ThomasLReplace the "?" in the following sequence:$ $ 2 7 10 13 14 22 26 27 28 31 49 53 54 57 78 79 ? 90 101 106 109 110 111

1:37 PM
I’ve made a small CCCC edit I fear is needed for fairness; sorry.
And a hint: the first letter is T.
2:19 PM
He's about to get a kiss (3) = REX?
I know kiss is "X" but not sure how the rest resolves
maybe a bad clue
personally, I'd say: Headless dinosaur king (3)
"about" is sometimes used to clue "re" (regarding), see the second entry for "re" here: merriam-webster.com/dictionary/re
And "he" just refers to a man's name.
@Avi I wouldn't, because the "rex" in "T. Rex" literally means "king"
(but yes, this uses both "about" = RE, and "he" = [the answer is a man's name]"; I'm not a fan of the latter)
Neither am I.

Q: Two cards which product is not a square

ThomasLThere are 100 cards on a table numbered 1,2,...,100. What is the maximum number of cards, which can be selected such that no two cards have a product, which is a perfect square? Example: you cannot choose the cards with number 27 and 48, as $27*48=81*16=36^2$

Q: What comes next in this sequence, and why?
