A Multiplication Based Logic Puzzle

430 and Level 4

The factors of 430 are listed after the puzzle.

What interesting fact could I say about the number 430? I did a little research.

Biblewheel.com quotes a verse from Galations 3:17 in the Bible: “And this I say, that the covenant, that was confirmed before of God in Christ, the law, which was four hundred and thirty years after, cannot disannul, that it should make the promise of none effect.” Biblewheel states that 430 means the law, just as 666 means the beast.

Stetson.edu/numbers says that 430 “is the number of necklaces possible with 6 beads, each being one of 4 colors.” If I understood what that means in English, I’m sure I could construct it mathematically. I know it can’t mean 6 Choose 4. If you understand what it means, please comment.

  2. I’m struggling with that necklace thing. My first thought was 4^6 which is 4096. Then I thought, if each bead has to be a different colour to the adjacent bead, the number is 4*3^5, which is 972. You could halve that, on the grounds that half of the possible necklaces are the same but turned around, but that still gives you 486 possible necklaces.
