Number of different necklaces using $m$ red and $n$ white pebbles Yes, you're right. But things get different when they are not coprime. |

5 moving points in plane, one goes to infinity Nice construction, but you didn't notice the condition that No three of the lines should intersect in one point. Without this condition, making an example for $5$ is also easy, just consider $5$ points on sides and one diagonal of a square. |

5 moving points in plane, one goes to infinity @alex.jordan: I meant that only at the initial position, non of the points is an intersection point of two lines. It's obvious when they start moving, they may meet each other. |

5 moving points in plane, one goes to infinity To your first question, yes. Each point has it's own track. Also, each point move at its own distinct constant speed. |

Minimum number of circles in a rectangle with no line in rectangle not intersecting any of them Thanks, edited. Also it suffices to cover two diagonals to have each line intersecting at least one of them, but I'm intersected in the minimum number of such circles. |
