Rearrangement

Arrangement of tiles is irrelevant, as long as two groups of tiles form the identical sequences.

Formation

This yaku is usually presented as three groups of consecutive pairs. However, the rule interpretation views them as a two sequences. Potential acquisition of this yaku is best recognizable when five out of the six tiles are present in the hand.
