That is, we are 100+N kilometers from the North Pole, at any point in this circle. We go 100 north, now we are in N kilometers. We go to 100 west (or east, I don't remember the conditions), we cut around the pole strictly a whole number of turns. Go 100 south, return to the starting point.
Thus, we are satisfied with the infinite number of points lying on an infinite number of parallels, which, on a glass-kilometer arc lying on the meridian, are separated from the arbitrary parallel having any circle of the species 100/I.
Was that meant?
How is that traveler who was taken to the club of the round-the-world, although he did more (has reached the pole), but formally did not swim around the globe? The actual reason was that the Pole was cooler than the world, and the formal reason was that he said that he stood on the Pole and turned a little.
