# Accumulates the frequencies of all n-tuples of bits in a list\n\
# of random integers and compares the distribution thus generated\n\
# with the theoretical (binomial) histogram, forming chisq and the\n\
# associated p-value.  In this test n-tuples are selected without\n\
# WITHOUT overlap (e.g. 01|10|10|01|11|00|01|10) so the samples\n\
# are independent.  Every other sample is offset modulus of the\n\
# sample index and ntuple_max.\n\
