• The first 10 digits of the fifth root of n contain the digits 0-9.at n=32A119520
• Triangle read by rows: T(n,k) is the number of specially labeled bicolored nonseparable graphs with k points in one color class and n-k points in the other class. "Special" means there are separate labels 1,2,...,k and 1,2,...,n-k for the two color classes (n >= 2, k = 1,...,n-1).at n=47A123301
• Primes formed by an m-digit prime concatenated with its last (m-1) digits, for m > 1.at n=31A252667
• Indices of hexagonal numbers (A000384) which are also centered hexagonal numbers (A003215).at n=5A253175
• Centered 11-gonal (or hendecagonal) primes.at n=17A262344
• Number of simple graphs on n unlabeled nodes with maximum degree exactly 2.at n=29A324740
• a(n) is the largest k such that k^2 has a maximal Hamming weight A357658(n) in the range 2^n <= k^2 < 2^(n+1).at n=29A357660
• Primes having only {4, 6, 7} as digits.at n=15A385794
• Primes having only {0, 4, 6, 7} as digits.at n=28A386072
