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.
When I published the solution to this problem, I assumed that no one would likely find a better solution. But recently, I recieved an email from a Bryce Herdt informing me of a better solution by changing each 9 in the current solution grid with an 8 and changing each 8 with a 9. This produced a grid with 101 consecutive three digit integers.
