Thus power subgroups behave better than omega subgroups, a phenomenon that one also encounters in other situations
Subgroups, cyclic groups and generators 2.1 de nition
A subgroup of a group g is a subset h g which is also a group using the same operation as in g When h is a subgroup of g, we write h g. Let p be a prime In particular, if ω generates ω1 and e has a canonical subgroup ce,
We need to nd a smooth homomorophism from r to g using lx This homomorphism is provided by the ow or integral curve of lx But let us work this out in more. For each integer , let p e se( ) be the set of subgroups of g e order and put se( ) = |se( )
Based on theorem l, frobenius proved
P theorem 2 (frobenius [fr1, section 4.i]) 1 subsets and subgroups we have seen many examples of groups contained in larger groups For example, (z, +) is contained in (q, +), which itself is contained in (r, +)
