Query: The secret symmetries of the AdS/CFT reflection matrices   We find new twisted Yangian symmetries of the AdS/CFT reflection matrices for
the Y=0 maximal giant graviton and D5-brane. These new symmetries originate
from the known secret symmetries of the Yangian symmetry of the AdS/CFT
S-matrix.
