Basic Examples

Project a rank-2 tensor onto the totally symmetric class:
In[1]:=
YoungProject[{{1,2},{3,4}},YoungTableau[{2}]]
Out[1]=
1,,,4
5
2
5

Project the same tensor onto the antisymmetric class:
In[2]:=
YoungProject[{{1,2},{3,4}},YoungTableau[{1,1}]]
Out[2]=
0,-,,0
1

Projection is idempotent:
In[3]:=
YoungProject[YoungProject[{{1,2},{3,4}},YoungTableau[{2}]],YoungTableau[{2}]]===YoungProject[{{1,2},{3,4}},YoungTableau[{2}]]
Out[3]=
True
