Input the words ONE through EIGHT into a 5x5 square,
so that the numbers read in any of the 8 cardinal directions.

I was expecting some sort of trick with how 'THREE', 'SEVEN', and 'EIGHT' were placed.  But the solution I found has all of them in parallel:

THREE
SEVEN
SIX.O
FOURW
EIGHT

'ONE', 'TWO', and 'FIVE' are the only numbers not reading in the normal left-to right orientation.
