comment A set for which it is hard to determine whether or not it is countable.
A quick google search yields deepblue.lib.umich.edu/bitstream/2027.42/32762/1/0000133.pdf , but I don't know what the "canonical" reference is.

comment Random knot on six vertices
@Joseph: Thanks. It seems so obvious now. I guess that will teach me not to make conjectures in the middle of the night based on very little numerical evidence...

comment Consecutive integers with many prime factors
@drvitek: I agree that this is a very elegant answer. Thanks for observing that it also provides an upper bound. It's actually about 5 orders of magnitude better in the case $m=n=4$, but still too large to be of practical value. We can just let k run from 0 to m-1 instead and get $\prod_{i=1}^{16} p_i$ which is around 3E19.
