David A. Corneth, Table of n, a(n) for n = 1..10000 (first 250 terms from Reinhard Zumkeller, terms 251..500 from Branden Aldridge).
EXAMPLE
M(n) is the array in which m(x,y,z)=x*y*z for x = 1 to n, y = 1 to n and z = 1 to n. In M(7) the most frequently occurring numbers are 12 and 24. They occur 15 times, so a(7) = 15.
