#          Diehard Overlapping 5-Permutations Test.\n\
# This is the OPERM5 test.  It looks at a sequence of one mill- \n\
# ion 32-bit random integers.  Each set of five consecutive     \n\
# integers can be in one of 120 states, for the 5! possible or- \n\
# derings of five numbers.  Thus the 5th, 6th, 7th,...numbers   \n\
# each provide a state. As many thousands of state transitions  \n\
# are observed,  cumulative counts are made of the number of    \n\
# occurences of each state.  Then the quadratic form in the     \n\
# weak inverse of the 120x120 covariance matrix yields a test   \n\
# equivalent to the likelihood ratio test that the 120 cell     \n\
# counts came from the specified (asymptotically) normal dis-   \n\
# tribution with the specified 120x120 covariance matrix (with  \n\
# rank 99).  This version uses 1,000,000 integers, twice.       \n\
