So a 6-count step is normally double-triple-triple, which is even-odd-odd. And an 8-count is even-odd-even-odd. Note that odd rhythms need to be paired up, though not necessarily next to each other, in order for you to end up on the correct foot for the next move. Though if you end up on the wrong foot, then you simply change the next move's intial double into an odd rhythm to correct it -- eg, the "hitch step" which is effectively a kick-ball-change.
Dancing a triple without swing would be dividing the two beats evenly into thirds.
To swing the triple, the middle is delayed (closer to the last step than the first), but the two full weight changes still fall on the beats.
