Revealing mistake: When the simulant pulls the knife out of his chest, you can see the knife is a dummy. As the handle is pulled back, the blade does not move at all. (00:25:30)
Continuity mistake: After Lister and Ace do the 'awooga' dance, Lister locks change from being clumped together to being mostly behind his back. (00:21:40)
White Hole - S4-E4
Continuity mistake: When the Cat and Lister are trying to cook an egg with a bicycle powered hair drier, you can see the Cat holding a frying pan. When Lister gives up and gets off the bike, Cat picks up a spatula with his other hand and starts poking the egg with it. However, in the next shot, he is shown with both hands on his hips. It's an instant cut with the same conversation continuing, so he didn't have time to put them down. (00:15:25)
Revealing mistake: When the Dalai Lama explodes, there is a single shot where he has disappeared and a yellow cloth has taken his place just before the explosion. The cloth then lands in the background. (00:22:55)
Revealing mistake: The metal shelf the three spare heads sit on can be seen to move as spare head three speaks. (00:19:40)

Continuity mistake: When Rimmer's mother is talking to him while he is hung upside down, she is stood about a foot away from him in one shot, then in the next she is about three feet away. (00:01:45)
Revealing mistake: When Ghandi explodes, there is a single shot where he had disappeared before the explosion goes off. (00:22:35)
Answer: Presumably he does, but it's never been used in any material related to the show. He is the only Cat left (as shown in Series 1), so even if he had once had a name, nobody would know it.
