"One question for רועי סיני and Dave Keenan - I think in some recent post, we determined that the "canonical" versions of each feudal prime are not necessarily the two that are closest together, right? I had thought we determined that was the criterion that was best for some reason. What criterion are we using instead?"

I tried to reply to you on facebook, twice, but facebook claimed that my replies violate their spam guidelines! Then I tried to just tell you

*that*, on facebook, and apparently

*that*has disappeared too! Then I posted a link to this post. It seems that whatever I post now, vanishes without a trace. I think facebook has lost the plot.

My (supposedly-spammy) answer was:

In the old facebook thread Roee wrote:

"Dave Keenan, In fact, your choice of primes is not always the two closest in size. For example, F29/f29 is 1.733..., while (f29ϕ)/(F29/ϕ) is 1.510...

However, they are always either the best or the second best choice, because they are both between bϕ-b = b/ϕ and bϕ, where b is their equal golden part, which means the quotient between them is less than ϕ², and any time you multiply one of them by ϕ and divide the other by ϕ you either multiply or divide the directed quotient by ϕ². Anyway, I don't think this is a large enough issue to use the other choice instead in this case, because of the consistent normal forms they have."
