• Denominators of continued fraction convergents to sqrt(613).at n=11A042177
• This table shows the coefficients of combinatorial formulas needed for generating the sequential sums of p-th powers of binomial coefficients C(n,7). The p-th row (p>=1) contains a(i,p) for i=1 to 7*p-6, where a(i,p) satisfies Sum_{i=1..n} C(i+6,7)^p = 8 * C(n+7,8) * Sum_{i=1..7*p-6} a(i,p) * C(n-1,i-1)/(i+7).at n=26A087111
• Number of n X n binary arrays symmetric under 90 degree rotation with all ones connected only in a 1100-1111-0010 pattern in any orientation.at n=14A146704
• Number of length 4 1..(n+1) arrays with every leading partial sum divisible by 2 or 3.at n=20A257066
• Number of active (ON, black) cells at stage 2^n-1 of the two-dimensional cellular automaton defined by "Rule 419", based on the 5-celled von Neumann neighborhood.at n=7A272046
• Number of strict compositions of n with no three consecutive parts in arithmetic progression.at n=31A325849
