I feel quite honoured that the cosmos should treat me to such a splendid little coincidence, even if it is a theoretical one rather than a real one!
As a matter of fact, I did do the calculations for a non-spherical earth, & like Michael Behrend found nothing there.
Merton Sewage Works was my concession to symbolism at the expense of strict accuracy. Mathematically unforgiveable, of course, but great fun just the same. …
As for Michael Behrend’s SP 678 194, I wonder if the good people of Aylesbury are planning a sewage works around those parts?
I trust that this reply will serve to as-sewage Michael Behrend’s feelings of academic unease. (Apologies to those not fond of diabolical puns.)
