Vector subspace notation question

when dealing with vector subspaces, an example of a question asks:
if
x=(a,a,b)T (T is really a superscript)
is any vector in S, then...
what does that T superscript notation mean? does that mean transpose?
Thanks

It means you should swap rows for columns, so that matrix/vector becomes a column vector.
