:Is this a standard notation for multisets?  I haven't seen it before, but I haven't read much about multisets.  I do know that in non-mathematical writing, it's common to use x to indicate repetition, and the number of repetitions usually comes before the x.  So "1x(n-2)" is ambiguous.  I think "(n-2)x 1" would be clearer.  You could also just put "1, 1, ..., 1"; the number of 1s can be inferred from the fact that the multiset has n elements.

I used "<1> x (n-2)" in the hope that it would minimise ambiguity.
In this case the thing repeated tends to be much simpler than the repeat
count, so it would likely be harder to read if the order was reversed.
