Daniel C. Mayer, Define an "m-triple" to consist of three consecutive squarefree positive integers, each with exactly m prime divisors, Number Theory group on LinkedIn.com
EXAMPLE
a(1) = 3323705 = 5*7*11*89*97, a(1)+1 = 2*3*41*59*229 and a(1)+5 = 2*5*13*37*691 yield the first triple of consecutive squarefree numbers such that each of them is the product of five distinct primes.
PROG
(PARI) (back(n)=for(i=1, 2, until(issquarefree(n--), )); n); for(n=10^6, 2e7, issquarefree(n)||next; ndk==ndm&&ndk==5&&omega(n)==ndm&&print1(back(n)", "); ndk=ndm; ndm=omega(n))
