Formation
While the hand shows a complete 1-9 grouping from a particular suit, it is best to view as three separate groups of: 123, 456, and 789. This is particularly useful to note when needing to open the hand with such a combination.
Counter example
{{
Waiting for: or 
In this counter example, the tiles 1-9 for one suit are in the hand. However, ittsu would not be counted. In fact, this hand is lacks any yaku. The manzu are not grouped as 123, 456, and 789. Instead, they are grouped as 123, 567, and 789.
Compatability
^ Ippatsu requires riichi to be of any use.
