Appears in sequences
- The start of a record-breaking run of consecutive integers with a number of prime factors (counted with multiplicity) equal to 5.at n=4A067820
- a(n) is the smallest number that starts a consecutive block of n numbers with at least n prime divisors (counting multiplicity) each.at n=4A119654
- Numbers k such that k, k+1, k+2 and k+3 are products of 5 primes.at n=4A124729
- Smallest integer m such that the n consecutive numbers m, m+1, ..., m+n-1 have n prime factors each, counted with multiplicity; a(n) = 0 if no such number exists.at n=4A237201
- Numbers n such that 5 consecutive numbers starting with n are products of 5 primes.at n=0A267362
- Triangle read by rows: T(m,k) is the first number that starts a sequence of exactly k consecutive numbers with m prime factors, counted with multiplicity, if such a sequence is possible.at n=31A374449
- Square array T(n, k), n >= 2 and k >= 1, read by antidiagonals in ascending order, give the smallest number that starts a sequence of exactly k consecutive numbers each having exactly n prime factors (counted with multiplicity), or -1 if no such number exists.at n=32A375160
- Smallest number m such that m, m+1, m+2, m+3 and m+4 have exactly n prime factors (counted with multiplicity).at n=2A387505
