| Notes |
next: - first: Schenk_IBMNA/c-73
An earlier version (Oct. 2003) of this matrix was obtained from Olaf
Schenk, and appears here as Schenk_IBMNA/c-73. However, it differs
from the version posted on his web site as of Nov. 2006. The new
version appears here as Schenk_IBMNA/c-73b. The two matrices are very
similar, but not identical.
