In the 4x4 grid below, 32 consecutive two digit numbers (45 to 76) have been packed in it.
1 3 5 9
2 5 4 8
0 7 6 2
1 6 3 9
*****
The challenge: Pack as many consecutive 3 digit numbers as possible into a 9x9 grid. The numbers may be read from any direction. No leading zeros.
Thanks for pointing this one out to me Brian. I'll be writing a GA to look for good candidates the next time I get to a computer, in a couple of days. What a goodie - just the sort of thing I'm looking for!
