Then a(n) is the least k > 1+n*(n-1)/2 such that f(k, n) is a multiple of f(1+n*(n-1)/2, n). %C A093908 f(k, n) = A008279(n+k-1, n). 1+n*(n-1)/2 = A000124(n-1). f(1+n*(n-1)/2, n) = A057003(n). %C A093908 a(28) > 88*10^12. %e A093908 a(4) = 39 because 39*40*41*42 is divisible by 7*8*9*10. No %e A093908 smaller set gives a product that is a multiple of 7*8*9*10. %Y A093908 Cf.
