"There are over 330 rail stations within the Travelcard zones, and at
present each of 97,300 different station-to-station combinations has
its own set of fares."

Does this add up?

330 stations can come in 54285 combinations, or 108570 permuations
(which may be more appropriate as the fares may not be the same in
both directions(?)) .

If there were 441 stations there would be 97020 combinations, while
442 stations would give 97461, but 442 is a lot more than the wording
"over 330" would suggest.

312 stations would give 97032 permuations, 313 stations 97656, but
even assuming there are appropriate numbers of stations treated as
groups for ticketing, this isn't 97300 - though 97032 could lead to a
typo.

Obviously many of these fares will be the same amount, as no fare will
be GBP900, so they aren't deleting ones of the same amount from the
total.

So what am I failing to see? Perhaps an effect of the zonal fares
already in place, so (say) Waddon, West Croydon and Carshalton
Beeches (etc) don't have their own sets of fares?
