[parent] table of small Knödel numbers $K_n$ for $0 < n < 26$ (Example)

The following table lists small Knödel numbers $ K_n$ for $ 0 < n < 26$. I've been deliberately arbitrary about what is small: for some $ n$, especially even $ n$, there are plenty of Knödel numbers to choose from so I only go up to 100; while for some odd bases there are so few I go up to 1000. And of course for $ n = 1$, the $ K_n$ are the Carmichael numbers, of which there is only one less than a thousand: 561.

$ n$ $ m \in K_n$
