Young subgroup
From Encyclopedia of Mathematics
Let 
be a partition of 
into 
disjoint subsets. Then the corresponding Young subgroup of 
, the symmetric group on 
letters, is the subgroup
 |
where 
. Sometimes only the particular cases
 |
are meant where 
, where 
and 
is a partition of the natural number 
, i.e. 
, 
.
