- Cycle class sequence c(n) (the number of true cycles of length n in which a certain node is included) for zeolite HEU = Heulandite Ca4[Al8Si28O72].24H2O starting with a T4 atom.at n=14A019135
- a(n) = T(n,n), T given by A026584. Also a(n) is the number of integer strings s(0), ..., s(n) counted by T, such that s(n)=0.at n=14A026585
- a(n) = self-convolution of row n of array T given by A026584.at n=7A027282
- Numbers k such that sum of the divisors of k equals the sum of the reversals of the divisors of k. Numbers with all palindrome divisors are not in the sequence.at n=23A196677
