I can see how 70 is a "weird number" (divisors 2 + 5 + 7 + 10 + 14 + 35
= 74 and no subset adds up to 70), but can someone explain to me how
836 is considered "weird"?

2 + 11 + 19 + 22 + 38 + 209 = 301

Am I missing a divisor, because last time I checked 301 < 836.  When I
factor 836, I come up with 2 * 2 * 11 * 19 = 836.  Is this just one of
those cases where the internet is *wrong*?

Very confused,
