 Hipparchus on Compound Statements 
  (Hipparchus, to be sure, refuted this by showing that on the affirmative side there are 103,049 compound statements, and on the negative side 310,952.)" The exactly meaning of these numbers has been something of a mystery for Greek scholars. 
  For example, Heath's "History of Greek Mathematics" says "In pure mathematics [Hipparchus] is said to have considered a problem in permutations and combinations, the problem of finding the number of different possible combinations of 10 axioms or assumptions, which he made to be 103,049 (v.l. 
  This does not seem like enough information to pinpoint exactly what Hipparchus had in mind." It might be worth noting that the number 103,049 appears, slightly disguised, in another sequence in Sloane's Encyclopedia, namely M1659, which are identified as the number of "Royal paths in a lattice".
