- Could someone please explain to me a few basic things:
-
- What is the logic used to answer questions of the below type?
-
- 1) If the finite group G contains a subgroup of order 7 but no element
- (other than the identity) is its own inverse then the order of group G
- could be (a)27 (b)28 (c)35 (d)37 (e)42.
-
- It says that the correct anwer is (c). I know why we can eliminate (a)
- and (d) but don't know how to proceed further.
-
-
-
- Also could someone explain what is elementary Riemann and Lebesgue
- integration, and why fuctions can be integrable but now Riemann
- itegrable etc? I looked over a couple of books but did not quite get
- it.
-
-
- Thanks
