Discussion:

Paragraph 2 begins:

The size of the state is r.

However, the next sentence specifies a total of r+1 items in the textual representation of the state, r specific x's as well as a specific carry. This makes a total of r+1 items that constitute the size of the state, rather than r.

Proposed resolution:

We recommend the sentence be corrected to match:

The size of the state is r+1.

[ Jens: I plead for "NAD" on the grounds that "size of state" is only used as an argument for big-O complexity notation, thus constant factors and additions don't count. ]

[ Berlin: N1932 adopts the proposed NAD. ]
