  Two-mode squeezed number states (TMSNS) are natural generalization of
two-mode squeezed vacuum states. It has been known that every TMSNS is
entangled whenever the squeezing parameter is non-zero. For a pair of entangled
pure states Nielsen's majorization theorem tells us whether one state can be
transformed into the other state through local operation and classical
communication based on the majorization property on their probability
distributions of Schmidt bases. In this report we find two examples of
majorization relations for a set of TMSNS.
