To quote Matt Parker on the number (813826):
Sure, some would say that number is reverse tau, but I think of it as the 50th root of 50. https://oeis.org/A011469
No, Matt, face it: It's 2–1 for Team Tau now.
Ok so (314159) and (628318) are obviously pi and tau respectively, but what is (813826)?
Tau backwards
Ohhh ok I see it now
