EXAMPLE
T(4,2)=4 because bigomega(2)+bigomega(3)+bigomega(4)=1+1+2=4.
Triangle begins:
0;
1,1;
2,2,1;
4,4,3,2;
5,5,4,3,1;
MAPLE
with(numtheory): T:=(n, k)->add(bigomega(j), j=k..n): for n from 1 to 13 do seq(T(n, k), k=1..n) od; # yields sequence in triangular form
MATHEMATICA
T[n_, n_] := PrimeOmega[n]; T[n_, k_] := Sum[PrimeOmega[j], {j, k, n}];
Table[T[n, k], {n, 1, 10}, {k, 1, n}] // Flatten (* G. C. Greubel, Sep 03 2017 *)
