• Integers n for which the ratio phi(n)/pi(n) is smaller than for any subsequent n. Here phi(n) is Euler's totient function and pi(n) is the number of primes that are at most n.at n=35A080289
• Numbers n that raised to the powers from 1 to k (with k>=1) are multiples of the sum of their digits (and n raised to k+1 must not be such a multiple). Case k=14.at n=30A135199
• Denominators of row sums of the triangle (lower triangular matrix) log(F) with F:=A037027 (Fibonacci convolution matrix).at n=21A181350
• Numbers with prime factorization pqrstuv^2.at n=5A190381
• a(n) is the least number k that has exactly n divisors <= sqrt(k) of the form 4*j+3.at n=28A379683
