I, if i were into clobbering files, would take the liberty of editing
the file as follows:
(SETQ C 118937307725496656754857164120791261365228885.
D 6296488643826193618261.
Q (QUOTIENT C D)
R (REMAINDER C D)
C* (PLUS (TIMES Q D) R)
BMTLOSES (EQUAL C C*)
LISPLOSES (EQUAL R D))
and you will in fact find that LISPLOSES is T.
Sigh, yes, LISPLOSES is indeed true. Will investigate shortly. Notice
the representation of these numbers in base 8:
C = 5252525252525252525252525252525252525252525252525
D = 1252525252525252525252525
Q = 4000000000000000000000000
R = 1252525252525252525252525
Looks like that "one chance iin 2^35."?
