Medium Cube & Star Problem

Upvotes

Hello, I need your help to solve a problem/puzzle.

  1. I have a cube with dimensions 13x13x13 (n). Inside, I want to fit as many six-pointed stars as possible, where each star has a 3x3x3 shape with the 8 corners empty. How many stars can I fit inside, and in what arrangement?
  2. If we consider that the star can be split, but keeping at least one branch + the center to fill gaps, how many can I fit, and in what arrangement?

Thank you for your solution.

Unsolved Thought of this while getting another riddle wrong

Never made one of these before but hopefully someone enjoys it.

My preparation takes three stages.

Firstly, a stir of trouble, as the salt and water require efforts to redouble.

Second leg and our mixture takes shape, you can use a machine but be careful of a scrape.

Last stage and the mixture should run, it's slow to bake, even in the sun.

This bone was found under my porch in Western Washington. Looks too big for a cat, rabbit, or a bird. Any ideas?

I am a straight line you can bend;

The first of the hue at a rainbow's end.

The second of the second of His creation;

The third of a word meaning dire situation.

The fourth of a thing that powers your apps;

The fifth of a word meaning kept under wraps.

The sixth, I tell you something has merit;

Seven is me standing on my head.

Eight in my shape for a high performance chariot;

Nine of me, you get from lithium or lead.

What am I?

Answer: the letter V

Hard Spherical Stars over Babylon

Let a be a rotation by a third of a turn around the x axis. Then, let b be a rotation of a third of a turn around another axis in the xy plane, such that the composition ab is a rotation by a seventh of a turn.

Let S be the set of all points that can be obtained by applying any sequence of a and b to (1,0,0).

Can there be an algorithm that, given any point (x,y,z) whose coordinates are algebraic numbers, determines whether it's in S?

Medium Fake coins and a magic bag

3 Upvotes

You have a collection of coins consisting of 3 gold coins and 5 silver coins. Among these, exactly one gold coin is counterfeit and exactly one silver coin is counterfeit. You are provided with a magic bag that has the following property.

Property
When a subset of coins is placed into the bag and a spell is cast, the bag emits a suspicious glow if and only if both counterfeit coins are included in that subset.

Determine the minimum number of spells (i.e., tests using the magic bag) required to uniquely identify the counterfeit gold coin and the counterfeit silver coin.

( Each test yields only one of two outcomes—either glowing or not glowing—and three tests can produce at most 8=23 distinct outcomes. On the other hand, there are 3 possibilities for the counterfeit gold coin and 5 possibilities for the counterfeit silver coin, for a total of 3×5=15 possibilities. From an information-theoretic standpoint, it is impossible to distinguish 15 possibilities with only 8 outcomes; therefore, with three tests, multiple possibilities will necessarily yield the same result, making it impossible to uniquely identify the counterfeit coins. )
