Next generation pandavas

I have read that drapaudi and yudhishtra had a daughter named suthanu who was married to krishna satyabhama s son bhanu. And that this mentioned in vayu puran , harivamsa and even one of the post war sequence of Mahabharata.

If anybody can provide citation i will be grateful

And also citation for why abhimanyu was not able to learn how to exit chakravyuh. ? Have heard two different stories but I don't think vyasa mentions any of them . If mb does talks anything about it i would love if somebody can give citation

Thanks
