A Prat u'Chlal includes everything and Klal and a Klal u'Frat includes only the Prat.
According to Tana D'Vei R. Yishmael the second Klal of a Klal Prat u'Chlal does not have to be the same as the first Klal.
We cannot learn out of a Klal Prat u'Chlal more than what can be learned out of the second Klal. (1)
In Ma'arava they said that when there are two Kelalim next to each other we place the Prat between them and it is regarded as a Klal Prat u'Chlal.
R. Yishmael says that when there are two Kelalim next to each other it is learned out with a Ribuy Mi'ut and Ribuy. (2)
A Ganav does not pay Kefel for Karka, servants or Shetaros.
Rav says that a Ganav pays back the principle of a stolen object in accordance with its value at the time that it was stolen.
Someone who admits to a Knas is Patur, however if after he admits to the Knas and witnesses testify that he is Chayav it is a Machlokes whether he is Chayav to pay the Knas.
Every Parshah in the Torah that is repeated was only repeated for a Chidush that is found in the second Parshah which is not found in the first Parshah.
Although a Shomer who claims that the objects he was guarding was stolen only pays Kefel if he swore falsely a regular Ganav pays Kefel even without a Shevu'ah.
A BIT MORE
1. The second Klal includes items that are excluded from the Klal u'Frat because without the second Klal it would be a Klal u'Frat and it would only include the Prat.
2. With a Ribuy Mi'ut and Ribuy everything is included except for one item that is excluded from each Mi'ut.
