• Numbers k such that the period of the continued fraction for sqrt(k) contains exactly 31 ones.at n=35A031799
• Numbers k such that the decimal digits of k*(k+1) are a permutation of those of k*(k-1).at n=25A181775
• Numbers which contain only the digit 4 in their base-5 representation, with at most one exception. If the exception is the most-significant digit, it must be the digit 1, 2, or 3, otherwise the exception must be the digit 3.at n=43A188531
