triple features 100 100 100 100 100 100
Note that type 1 and 4 are linearly separable.
Note that type 2 and 6 have no information in the individual features.
If we use triples alone as input, we get perfect behaviour
Neither first or triples are what we're looking for.
We're looking for more or less perfect results, but some should be more difficult than others.
