 OFFSET 1,1 COMMENTS a(11) > 3*10^13. - Brian Trial, May 26 2017 LINKS Table of n, a(n) for n=1..10. EXAMPLE a(3)=33614 because 33614 is the start of a record breaking run of 3 consecutive integers (33614 to 33616) each having 6 prime factors; i.e., bigomega(n)=A001222(n)=6 for n = 33614, ..., 33616. MATHEMATICA bigomega[n_] := Plus@@Last/@FactorInteger[n]; For[n=1; m=l=0, True, n++, If[bigomega[n]==6, l++, If[l>m, m=l; Print[n-l, " ", l]]; l=0]] CROSSREFS Cf.
