• Smallest number strictly greater than previous one which is the sum of squares of two previous distinct terms (a(1)=1, a(2)=2).at n=14A008318
• Erroneous version of A008318.at n=11A064006
• For every positive integer m, let u(m) = (d(1),d(2),...,d(k)) be the unitary divisors of m. The sequence (a(n)) consists of integers of the form d(k)/d(1) + d(k-1)/d(2) + ... + d(k)/d(1).at n=29A229999
• a(n) = Sum_{d|n} n^tau(d).at n=25A345271
