Expressing Numbers with a Minimal Sum in Powers of 2
No, but notice that these integers are defined entirely with powers of 2 and that additions within these definitions add to the total cost. |

Consecutive Primes mod 3
@Jeppe I think this discovery is the "slight" effect already mentioned in comments. |

Particular case of Beal's Conjecture
Thanks. I guess I could now ask the question for exponents (3,4,5), which seems to be the new leading unproven candidate, but don't want to give @quid an ulcer! |

Particular case of Beal's Conjecture
@quid The order is important. This case is different:(3,4,3) or equivalently (4,3,3). |

Particular case of Beal's Conjecture
@quid Where is it "on the site linked to"? I don't think the Wikipedia page has any conclusion for this case, which is why I asked the question. |

yes, you understand it correctly |

All Integers from the Smallest Digit Stream with a Window Filter
I didn't know about DeBruijin. The answer is therefore yes, and, even more amazing, a contiguous window can always be used. So, that begs the question, can a stream be found for any given window? By your comment, I guess you extended my question to this already. Thanks. |

All Integers from the Smallest Digit Stream with a Window Filter
This might be confusing because my digits in the example ranged from 1 to 3. It's more normal to use a range from 0 to 2, so subtract one from all digits if that makes it more intuitive. |

coin reversal puzzle with one hand and two stacks
@Zack In similar words, I want to reverse one LIFO queue (i.e., a stack) using two other LIFO queues, but the reversed data needs to be in the original LIFO queue and the other two queues cannot feed each other directly. I'll give mathematicians a chance first because I think this is quite difficult and perhaps no algorithm is even known. |
