17.1.1 arbitrary-positional stream
a stream (described in clause 27) that can seek to any integral
position within the length of the stream.
Every arbitrary-positional stream is also a repositional stream
(17.1.16).

17.1.16 repositional stream
a stream (described in clause 27) that can seek only to a position that
was previously encountered.

These 2 definitions together imply the following self-contradictory
sentence:

"Every stream that can seek to any integral position within the length
of the stream can seek only to a position that was previously
encountered."

Yes, looks like the "only" in repositional is unnecessary.
