Cute little bison! Olahoma??? Is that near Oklahoma?

, Shiela. That reminds me: I had a student once named Lahoma. I was tempted, several times, when she asked a question, to say "OK, Lahoma."

Very nice Sue. Glad to be back

This the same park that had that beautiful statue of the pioneer woman and her son. Hal, I can see why it was so tempting to say "OK" to your student. Good thing you were not studying oak trees!!

11:42 My grandmother-in-law was named Lahoma, but I don't think she was HalT's student. To my knowledge she never went to school in S. Carolina. Plus, that would make HalT very, very old. Another nice bronze.

Great picture, btw, Sue!

Wonderful - puzzle, photo & banter!! Thanks everyone!

UP at f7, f8, pairs 48 at e46, 15 at h9,i7 and 36 at e19.
If 6 is in i5 or i6, then g1=6, e1=3, e9=6.
If e1=3, triple 127 at f123, and so f4=9, f5=3.
With e1=3, f5=3, e9 should be 3 which is not possible. So 6 cannot be at i5 or i6.
Thus i2=6.
UP 81.

A long path:
1)Start at 23,=>UP=25
2)(5):a2=a7-i7=i2,=>b2,c27<>5
3)(1):a9=h9-h4=f4-f1=a1,=>h6f3<>1
4 )(6):c4=c9-e9=e1-g1=g4,=>a4d9<>6
5)fc:(237)f123=(1)f1-(1)f4=(1)h4-(1)h9=(1-5)i7=(5-6)i2=(6 -8)d2=(8)d3
=>d23<>23 (two effective More...

Sorry. There are serious basic logic errors in my earlier 'proof'. Please treat that proof as withdrawn. I apologise.
