  We present a calculation of the four-loop anomalous dimension of the SU(2)
sector Konishi operator in N=4 SYM, as an example of "wrapping" corrections to
the known result for long operators. We use the known dilatation operator at
four loops acting on long operator, and just calculate those diagrams which are
affected by the change from operator length L > 4 to L = 4. We find that the
answer involves a Zeta[5], so it has trancendentality degree five. Our result
differs from previous proposals and calculations. We also discuss some ideas
for extending this analysis to determine finite size corrections for operators
of arbitrary length in the SU(2) sector.
