Hi Drew,
very long time no hear.
(Before Mally's decease IIRC)

Can you divulge what was so interesting about your
Hockey puck puzzle?

As Minigeek pointed out, 77 is a spectacularly pathetic
counter example.

77777 is blatantly obviously 7*11111

Okay: 77777 may be blatantly obvious: How about 77059?

7+7+0+5+9 = digital root 1

6n+1 = 7,4,9,6,3,9,6,3,9...... digital root
6n-1 = 5,2,8,5,2,8,..... digital root no 1 in either that I can see therefore it can't be prime if i have it correctly.

Happy memories!

But this "proof" really relies on the linguistic implication
that our degree of interest in entities is two valued: either i or uni.
In practice we all categorize our degree of interest on a continuous scale, probably multi-dimensional.

David

PS what is the second most boring number?

Logically the "proof" is seriously flawed. But somehow I think that it was not really intended to be analysed in a logical setting. It certainly can make for an interesting conversation on occasion (with a suitable amount of liquid enhancement to lubricate the tongues of course).
