 OFFSET 1,1 COMMENTS a(6) is greater than 50000000. - Tanya Khovanova & Alexey Radul, Jul 30 2006 a(8) > 10^13. - Donovan Johnson, Jan 31 2009 LINKS EXAMPLE Consider a(3): 98 = 2*7*7 (3 prime divisors), 99 = 3*3*11 (3 prime divisors), 100 = 2*2*5*5 (4 prime divisors). Hence 98 starts a consecutive block of 3 numbers with at least 3 prime divisors each. 98 is the smallest such number.
