Is there a common symbol for concatenating two (finite) sequences?

Say we have two finite sequences X=(x0,...,xn) and Y=(y0,...,yn).
Is there a more or less common notation for the concatenation of these sequences, like (X,Y)=(x0,...,xn,y0,...,yn)?


The comments suggest the following notations for the concatenation of X and Y:

  • XY (given by X^\frown Y);
  • XY (given by XY);
  • XY (given by X \cdot Y);
  • X (given by X \mathbin\Vert Y);

of which the first seems not to be in use for other concepts, making it especially suitable.
