• a(n) is the first term in a chain of at least n consecutive numbers, each having exactly m = 5 distinct prime factors.at n=4A087978
• Square array T(n, k), n > 1 and k >= 1, read by upward antidiagonals, give the smallest number that starts a sequence of exactly k consecutive numbers, each having exactly n distinct prime factors (counted without multiplicity), or -1 if no such number exists.at n=32A375287
