• Product of 8 successive primes.at n=3A046326
• Product of primes between n and n^2.at n=5A109819
• Transpose of square array A255483.at n=58A276578
• a(n) = where A284259 for the first time obtains value n (positions of its records).at n=8A284262
• a(1) = 1; thereafter a(n) = a(n-1) / lpf(n) if lpf(n) divides a(n-1), otherwise a(n) = a(n-1) * lpf(n), where lpf is the least prime factor function A020639.at n=33A337643

• Column 0 of the irregular triangle A355588.at n=36A355952
• a(n) = denominator((prime(n)-1)/prime(n)#), where prime(n)# = A002110(n) is the n-th primorial.at n=10A356094
