I have a new game for you. I’ve written about the location app\/website What3Words<\/a> before. If you don’t already know what it is, click on the link or download the app. It’s a way to identify any spot on Earth using only three words.<\/p>\n

The challenge is as follows: Find three distinct points using What3Words (W3W) that produce a triangle of minimum perimeter length and that follow these rules:<\/p>\n

    \n
  1. If point 1 is in the W3W form of A.B.C, point 2 must be in the form B.C.D, i.e. the W3W address must start with the second and third words of the original W3W.<\/li>\n
  2. Point 3 must have W3W address C.D.E.<\/li>\n
  3. The total distance you re trying to minimize is the straight line distance from Point 1 to Point2 + the distance from Point 2 to Point 3 + the distance from Point 3 to Point 1.<\/li>\n
  4. Points may not be duplicated, i.e. all three points are separate.<\/li>\n<\/ol>\n

    I chose a random point not too far from my house that had three short words I knew were used by W3W and tried to find the best triangle I could starting with that seed. I found one of 37.327078 miles total. The points are:<\/p>\n

    snack.bump.rang
    \nbump.rang.tuck
    \nrang.tuck.affair<\/p>\n

    See if you can beat that.<\/p>\n
