 A067822 The start of a record-breaking run of consecutive integers with a number of prime factors equal to 7. 5

 OFFSET 1,1 LINKS Table of n, a(n) for n=1..8. EXAMPLE a(3) = 3145310 because 3145310 is the start of a record breaking run of 3 consecutive integers (3145310 to 3145312) each having 7 prime factors; i.e., bigomega(n) = A001222(n) = 7 for n = 3145310, ..., 3145312. MATHEMATICA bigomega[n_] := Plus@@Last/@FactorInteger[n]; For[n=1; m=l=0, True, n++, If[bigomega[n]==7, l++, If[l>m, m=l; Print[n-l, " ", l]]; l=0]] CROSSREFS Cf. A001222, A067813, A067814, A067820, A067821.
