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:
- X⌢Y (given by
- XY (given by
- X⋅Y (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.
