Polydorus died while Labdacus was a child, leaving Nycteus as his regent, although Lycus soon replaced him in that office. When Labdacus had grown, he briefly ruled Thebes. He died while he was still young, after he lost a war with the king of Athens, Pandion, over their borders. Apollodorus writes that he, like his cousin Pentheus, was ripped apart by women in a bacchic frenzy for disrespect to the god Dionysus. Lycus became regent once more after his death, this time for Labdacus's son, Laius. His descendants were called the Labdacids, and included his son Laius, who fathered Oedipus; Oedipus's children were Polynices, Eteocles, Antigone, and Ismene.

The number N refers to the regency preceding the reign of the Nth king. Generally this means the regent served the Nth king but not always, as Creon (A9) was serving as regent to Laodamas (the 10th King) when he was slain by Lycus II (the usurping 9th king).
The letter A refers to the regency sequence. "A" is the first regent, "B" is the second, etc.
